 Recent blue crab occurrences and its dis- 

 tribution in the Mediterranean. In the last 

 10 to 15 years the blue crab has established 

 itself in the eastern Mediterranean and can 

 be considered part of the European fauna.

 retinal pigment migration. Biological Bulletin 

 (Woods Hole), vol. 70, No. 2, p. 159-184. 

 Specimens of Palaemonetes vulgaris were 

 injected with eyestalk extract from six 

 species of decapod crustaceans. Stalk 

 extracts from the eyes of C. sapidus had no 

 effect on the retinal pigments of the test 

 animals.

C. sapidus was one of the species from 

 which eyestalk extracts were used to test 

 retinal pigment migrations. References to 

 results of various blue crab studies con- 

 cerning calcium metabolism and localiza- 

 tion of the source of chromatophorotropic 

 hormone. 



extracts were tested by injection into two 

 species of prawns. In the blue crab, injected 

 sinus gland extracts caused only slight 

 light-adaption, but extracts of eyestalks 

 without the sinus gland produced a 

 response near that obtained with extracts 

 of whole eyestalks.

Experiments on Astacus trowbridgii and C.

 sinus gland in cases of physiologically 

 induced hyperglycemia and the resem- 

 blance between experimental hyper- 

 glycemia in crustaceans and the excitment 

 hyperglycemia of higher vertebrates.

Included in a section on metabolism of

 mary of the work of various other authors 

 on hyperglycaemic control mechanisms 

 (eyestalk and other tissues) of Callinectes.

 crustacean muscle. Biological Bulletin (Woods 

 Hole), vol. 82, No. 2, p. 207-214. 



The quick and slow contractions of the 

 skeletal muscles of C. sapidus, Libinia, and 

 Homarus were investigated and correlated 

 with "twitch" and "contracture" of verte- 

 brate muscle.

 arthropods. American Journal of Physiology,

Studies on the blue crab, lobster, and 

 spider crab indicated that selective excita- 

 bility and reciprocal inhibition is not 

 limited to claw muscles but is general in the 

 appendages of arthropods.
