 bution as a mechanism for membrane 

 potentials and potassium and chloride ion 

 distributions in crab muscle fibers. Compara- 

 tive Biochemistry and Physiology, vol. 26, 

 No. 3, p. 761-792. 



The adductor muscle of the walking leg of 

 the blue crab was studied with respect to 

 the nature of the resting membrane poten- 

 tial of the muscle fiber and the ionic 

 distributions that contribute to this poten- 

 tial. Cable constants were determined on 

 surface fibers and ion analysis of whole 

 muscles. Results support the hypothesis 

 that the striated muscle fibers are charac- 

 terized by a Donnan-like distribution.

Calcium used by soft-shell crab for harden- 

 ing of shell is not present at time of molt, 

 but is absorbed from sea water during 

 hardening.

 of salt flat areas on Aransas National Wildlife 

 Refuge, Texas. Publications of the University

 No. 2, p. 103-119. 



Collections of invertebrates (1946) made 

 on salt flat areas, in a ditch, and on the bay 

 shore indicated that the blue crab, a peneid 

 shrimp, and a grass shrimp were the most 

 abundant decapod Crustacea. Life history 

 of each species collected is presented.

Blue crabs, particularly young, are normal 

 residents of these coastal lagoons of Texas 

 and occur in salinities ranging from about 4 

 to 60 p.p.t.

 References to blue crab include their para- 

 sites, Carcinonemertes carcinophila (indi- 

 cates the reproductive history of the host), 

 and Loxothylacus texanus (causes castra- 

 tion). Also referred to are the frequent 

 summer mortalities of blue crabs, shrimp, 

 oysters, and fish in Offatts Bayou, possibly 

 due to poisonous dinoflagellates. Observa- 

 tions of blue crabs on oyster beds has shown 

 they prey almost entirely on parasitized 

 oysters which cannot close their shells as 

 tightly as normal oysters.
