Redescription of female Acetes johni Nataraj occurring in Mumbai (Bombay) waters
A redescription of the female Acetes johni Nataraj with suitable figures is given
in view of some additional features observed
Occurrence of Acetes johni Nataraj and A. japonicus Kishinouye in Bombay waters
Aceies indicus H. Milne Edwards constitutes an important fishery iu Maharashtra State. On a close
study of samples collected from Sassoon Dock and Versova, two principal landing centres ior Acetes,
it was observed that two more species were present in the catches. They were identified as Acetes johni
Nataraj and Acetes japonicus Kishinouye. Though a formal record exists for A. johni from
plankton collection off Saurashtra and Kerala Coasts, the fishery value for the species is reported for the
first time
A Tax on Work for the Elderly: Medicare as a Secondary Payer
Medicare as a Secondary Payer (MSP) legislation requires employer-sponsored health insurance to be a primary payer for Medicare-eligible workers at firms with 20 or more employees. While the legislation was developed to better target Medicare services to individuals without access to employer-sponsored insurance, MSP creates a significant implicit tax on working beyond age 65. This implicit tax is approximately 15-20 percent at age 65 and increases to 45-70 percent by age 80. Eliminating this implicit tax by making Medicare a primary payer for all Medicare-eligible individuals could significantly increase lifetime labor supply due to the high labor supply elasticities of older workers. The extra income tax receipts from such a policy would likely offset a large percentage of the estimated costs of making Medicare a primary payer.
Solenocera indica Nataraj, one of the commercially important penaeid prawns of Indian waters as a synonym of Solenocera crassicornis (H. Milne Edwards)
The validity of the specific name Solenocera crassicornis (H. Milne Edwards, 1837) is discussed nad Solenocera indica Nataraj (1945), a commercially important penaeid prawn from Indian seas is shown to be a synonym of the former

Synopsis of biological data of the Penaeid prawn Solenocera indica Nataraj, 1945
In India the species is found all along
the west and east coasts. Ahmad (1957) and
Nataraj (1945) recorded it from East Pakistan.
The material from which the original description
was made was partly obtained from the
Mergui Arohipelago and Singapore. Recently
Hall (1956, 19627 reported the species from
the west coast of Malaysia, Kubo (1949) recorded it from North Borneo
and Cheung( 41960, 1963) from around Hong
Kong. In terms of the FAO areas code (see
Holthuis and Rosa, 1965) it is recorded from
parts of sea areas ISW and ISEU, and from the
coasts of land areas 423, 425, 433, 436 and
42
Studies on the fishery and biology of 'ridge-back shrimp' Solenocera choprai Nataraj occurring off Maharashtra coast
Penaeid prawns belonging to the genus Solenocera have been reported to have fishery value
only off Northwest coast of India. The species exploited from the shallower regions of the coast
has been identified as Solemera crassicornis H. Milne Edwards, caught mainly in bag nets (Dol
and Bhokshi).
Another species S. choprai Nataraj was recently reported to have considerable fishery value
along Maharashtra coast, landed exclusively by mechanised trawlers, operating at 40-70 m 'depth
zone. This was found to contribute about 5% of the total penaeid catches from the region. The
fishing ground lies off Murud-Harnai coast.
S. choprai has'been recorded only from the Northwest coasts of India. This species bears a
very close resemblance to S. alticarinata Kubo. The salient features that help in its identity, along
with notes on its fishery and biology are presented, covering a period of ten years from 1977-1986.
The fishery for S. choprai was found to be highly seasonal from March to June for most of the
years, sometimes extending upto September. The observations were carried out at Sassoon dock, an
important landing centre for penaeid prawns in the state of Maharashtra. An export potential exists
for this species as it grows to a fairly large size. It is comparable in size to S. crassicornis which
is presently exported in good quantities to countries like Japan
Orbione digitata spec. nov. (Isopoda: Bopyridae), parasite de Solenocera choprai Nataraj (Decapoda: Penaeidae)
Nous remercions vivement M. le Professeur L. B. Holthuis (Leiden) qui nous a aimablement envoyé à déterminer les deux couples de Bopyres ci-dessous décrits. La récolte de ces derniers s'avère d'ailleurs des plus intéressantes, tant du point de vue taxonomique qu'éthologique. Tout d'abord, parce qu'il s'agit d'un nouvel Orbioniné et que, d'autre part, sur la cinquantaine de Pénéides parasités par ce groupe d'Isopodes, on ne connaissait jusqu'ici qu'une seule espèce du genre Solenocera infestée.
Orbione digitata spec. nov.
Matériel examiné. — ♀ holotype + O'allotype et 1 ♀ + l ♂, sur Solenocera choprai Nataraj; Inde, Madras, 19.iii. 1979; J. C. Miquel coll. (Rijksmuseum van Natuurlijke Historie, Leiden, N° Crust. I. 6409 (holotype et allotype) et I. 6910 (paratypes).
Description. — Femelle (fig. la): Longueur 17,4 mm; largeur 11,5 mm; pléon 5,2 mm. Asymétrie pratiquement nulle.
Céphalon renflé, son bord postérieur trilobé et quelque peu fissuré. Yeux absents. Lame frontale légèrement déprimée au milieu, sa longueur n'atteignant pas la moitié de celle de la tête (0,44). Antennules très écartées de trois articles; antennes presque deux fois plus longues, paraissant comprendre cinq articles.
