Reprint and inclusion of two separate 

 works under one cover. A 123 page bibliog- 

 raphy (published in 1939) gives seven 

 references on the genus Callinectes. 

 Although the genus is not referred to in the 

 second work, Larvae of decapod Crustacea 

 (published in 1942), it does contain perti- 

 nent information on development, 

 morphology, locomotion and distribution 

 of decapod larvae in general. The group 

 Brachyura was said to be so large and 

 varied that only a relatively few larvae 

 could be assigned to genus with any 

 certainty.

Measured were the Na + concentration of C. 



sapidus hemolymph in crabs acclimated to 



different salinities, potentials in vivo 



between blood and medium, potentials and 



oxygen consumption of isolated gill, and 



the influxes and effluxes of Na + and CI" in 



different preparations.

The transepithelial potential inside of iso- 

 lated blue crab gills with respect to the 

 external medium was measured. Influxes 

 and effluxes of Na^4 and Cl36 were 

 measured in 50 percent, 100 percent, 150 

 percent, and choline Ringer's solution.

 Biological Bulletin (Woods Hole), vol. 125, 

 No. 2, p. 379. 



The potential inside the afferent vessel of 

 isolated blue crab gills was measured at 

 different salinities. It was postulated that 

 negative gill potential results from passive 

 loss of sodium, and that positive potential 

 is due to active uptake of sodium exceeding 

 the passive loss.

 Abstracts, vol. 23, No. 8, p. 3041. 



The percentage length increase for the 

 mature molt of female crabs in three 

 different saline waters and under controlled 

 laboratory conditions indicated that 

 neither the population of the crabs nor the 

 salinity variation resulted in significant 

 difference in length increase. Hemolymph 

 calcium fluctuated markedly during the 

 premolt period, and hemolymph- 

 to-sea-water-calcium ratios differed signifi- 

 cantly among molt stages for each salinity.

 related to environmental salinity during 

 ecdysis of the blue crab, Callinectes sapidus 

 Rathbun. Physiological Zoology, vol. 37, No. 

 3, p. 247-258. 



Water content maintained through the molt 

 in three salinities was similar. Hemolymph 

 calcium fluctuated during the premolt 

 period in three salinities but always fell to a 

 similar postmolt value. Statistical analysis 

 of ratios of hemolymph to sea-water 

 calcium. Length increments showed no 

 significant differences among crabs at 

 various salinities.

 Field studies at three different saline 

 environments showed no significant dif- 

 ferences in percentage increase in body size 

 among three groups of crabs.
