paracrystal is too complex to allow further conclusions. The pattern of 

 peptides from CNBr cleavage of carboxypeptidase-treated Mereenaria paramyosin 

 differs from the usual pattern in complete loss of 9,000 molecular weight 

 peptide, one of the 7 final products of CNBr digestion, suggesting that this 

 peptide is C-terminal. - J.L.M.

The coiled-coil structure: Identity of the two chains of Mevcenaria 

 paramyosin. J. Molec. Biol. 98(4): 665-673. 



The main conclusion is that the two chains of paramyosin from red portion of 

 Uercenavia mere en aria adductor muscle are very similar, if not identical. 

 Close similarity or identity of the two chains, and polar paracrystal 

 structures observed by electron microscope, suggest that the two chains of 

 paramyosin are parallel. - J.L.M.

Production of shellfish feed by continuous algal culture. Proc. Natl. Shellf. 

 Assn. 63: 10-11 (abstract). 



7An apparatus was developed which can produce a sustained daily yield of 2x1011 

 cells consisting of 2 to 5 g ash-free dry weight of Monoehrysis lutheri . This 

 is considerably greater than what could be produced with the same space and 

 effort with traditional batch cultures. This 32-1 apparatus produced algal 

 cells with protein content that varied from 7 to 45% of dry weight, which was 

 less orderly than the product of a one-liter continuous culture experiment. 

 The large unit produces enough food for millions of clam larvae, thousands 

 of seed animals, or a few adults. - J.L.M.

Abundance of the hard clam Meveenavia meveenavia in relation to environmental 

 factors. Ecology 38(1): 123-128. 



Chincoteague Bay in Maryland is shallow. Much of the area has a depth of 

 only 2 to 4 feet. Maximum in the channels is 8 feet, except where strong 

 tidal currents have scoured troughs 2 to 4 feet deep. The high evaporation 

 rate produces high salinities in summer, up to 39°/oo. Increased rainfall 

 in winter and spring, and a lower evaporation rate, reduce salinities. In 

 June to August 1953, 93 stations were sampled, distributed through 100 square 

 miles in the Maryland region of the Bay. Distribution correlated well with 

 Dottom types, with shell, sand, sand-mud, and mud in decreasing order of 

 abundance. Higher densities of clams were also correlated with stronger 

 currents. Numbers of clams were apparently excluded from certain parts by 

 unfavorable low spring salinities and low summer ocean temps. Clams were 

 more abundant in deeper water. Raking is most often used in summer. Areas 

 sampled in 1952 showed a 33% decrease in abundance. An area on the eastern 

 margin is subjected to intense fishing pressures. Here, the clam population 

 declines rapidly when reduced setting reduces replacement of young clams. 

 For the first time, clams were dredged on a large scale in the central part 

 of the Bay during the winter of 1952-53. Here also this reduced the 

 population by about 33%. - J.L.M.

Status of the name Venus. Ecology 38(1): 160-161. 



Two groups once included in the genus Venus were sufficiently distinct to 

 have been recognized as subgenera. One has a reduced anterior lateral hinge 

 tooth and contains mostly eastern Atlantic species. The other has no such 

 tooth, and contains the American species. Each group has had a separate path 

 in recent evolution. Reduction of the anterior lateral hinge tooth is a case
