Malacobdella grossa in Pitar movvhuana and Mevcenavia campechiensis . Nautilus 

 81(2) : 37-40. 



The commensal nemertean M. grossa was found in 91 of 104 M. campechiensis from 

 13 locations off Cape May, N.J. to off Cape Charles, Va. Most hosts had one 

 nemertean; one had 2, another 4. The nemertean has also been reported from 

 M. mevcenavia on the Atlantic coast of North America and Venus mevcenavia on 

 the coast of Europe by Coe (1943) , abstracted elsewhere in this bibliography.

Summary of Florida commercial marine landings, 1960, and an analysis of the 

 catch and effort of certain species. Univ. Miami, Inst. Mar. Sci. , Mar. 

 Fisheries Research Rept. to Fla. State Bd. Conserv., 32 p. 



The list of common and scientific names of species landed in Fla. on p. 31 and 

 32 identifies hard clams as Mevcenavia mevcenavia and M. campechiensis . 

 Presumably they are not listed separately in catch statistics. - J.L.M.

Growth Rhythms and the History of the Earth's Rotation. Conclusions. 

 John Wiley & Sons, London: 535-5 38." 



This volume contains many important references to Mevcenavia mevcenavia 

 which are abstracted elsewhere in this bibliography under names of chapter 

 authors. The concluding section contains the following comment on hard 

 clam research: "Thompson's laboratory studies of Mevcenavia confirm 

 Mevcenavia growth periodicities described by the Yale group of Rhoads, 

 Pannella and MacClintock. Moreover, they further establish a link between 

 a behavioral process (gaping) and increment production. Thompson also 

 believes that her work establishes the existence of an internal biological 

 clock in Mevcenavia, independent of the environment. This conclusion should 

 be the subject of interesting discussion between the endogenous and exogenous 

 schools of biorhythm workers." - J.L.M.

In some Mevcenavia mevcenavia from Chincoteague Bay were amorphous blue 

 bodies consisting of Feulgen positive organisms belonging to the 

 Chlamydiaceae. Some of these Chlamydia sp. were in turn infected with a 

 virus. This was the first report in the United States (attributed to Otto 

 et al. 1975 and Harshbarger et al. 1975) of phagelike particles in rickettsia- 

 like organisms of aquatic invertebrates. - J.L.M.
