No specific mention of Meraenaria (Venus) meraenaria, but the paper has 

 general application. Class Bivalvia, Subclass Lamellibranchia, Order 

 Heterodonta. Gills eulamellibranch, and shell less modified than in 

 Anisomyaria, with adductors similar. Hinge dentition is of the "heterodont" 

 type. Mantle edges usually united at one or more points ventrally, and 

 often produced posteriorly into siphons. Shallow or deep-burrowing, or 

 occasionally surface-living. - description verbatim from text - J.L.M.

Florida shellfish toxicity following blooms of the dinof lagellate, 

 Gymnodinium breve. Fla. Dept. Nat. Res., Div. Marine Resources, Mar. 

 Research Lab., St. Petersburg, Tech. Ser. 60, ix+26 p. 



Shellfish toxicity was detected twice, in August and November 1967, and 

 January 1968, following outbreaks of red tide caused by G. breve. Toxicity 

 determinations were made on Crassostrea virginica at all stations except TX2, 

 near Sarasota. At that station, clams were sampled, but the species is not 

 given. Toxicity at station TX2 was moderate, and lasted a relatively short 

 time. - J.L.M.

Water-borne infectious hepatitis. New England J. Med. 261(14): 703-708. 



Jaundice epidemics have been attributed at times to water-borne transmission 

 since the 19th century, but this mode of spread of infectious hepatitis was 

 not definitely recognized as an epidemiologic entity until recently. 

 Infectious hepatitis is the first viral disease for which a water-borne 

 route of infection has been generally accepted. Such a route also has been 

 postulated for poliomyelitis but no conclusive evidence was available at 

 time of writing. The paper does implicate some foods, including oysters, as 

 vehicles, but hard clam is not mentioned. The paper ends with a note that 

 it was to be concluded, presumably in a later issue of the same journal.

 drinking water, either proven or suspected. Shellfish-related infections 

 are not discussed. - J.L.M.
