Gallianassa gigas^ Dana. 



Callianassa gigas, Dana, U.S. Ex. Exp., Crust, i. 212, pi, xxxii. fig. 3 : 

 Stimpson, Crust. & Echin. P. S, N. A. p. 49. 



I have not met with this species in the vicinity of San 

 Francisco ; nor does it occur among the numerous species of 

 Crustacea, including two new Thalassinidea, collected by 

 Fisher on the coasts of the Gulf of California. 



Dana met with it in Puget Sound. 



Callianassa longitnana^ Stimpson. 



Callianassa longtmana, Stimpson, op. cit. p. 50, pi. xxi. fig. 5. 



This species, originally collected at Fort Steilacoom, Puget 

 Sound, by Dr. Suckley, occurs also at Santa-Rosa Island, 

 one of the Santa-Barbara group, at San Diego, and at San- 

 Quentin Bay, Lower California. Doubtless it occurs at points 

 intermediate between these widely separated localities. 



Callianidea typa^ M. -Edwards. 



Callianidea typa, M.-Edwards, Hist. Nat. des Crust, pi. xxv. his, 

 figs. 8-14. 



It was with some surprise that I found, among other speci- 

 mens of Crustacea collected by Mr. W. J. Fisher in the 

 Gulf of California, some examples of this species, first col- 

 lected by Messrs. Quoy and Gaimard upon the coasts of New 

 Ireland. After careful examination I cannot detect any 

 difference between my specimens and the figures given by 

 Milne-Edwards, although the localities are so wide apart. 



The specimens, three in number, were taken at La Paz at 

 low tide. 



Total length of second largest specimen 50 millims. ; length 

 of smaller hand 10, of larger 15. Length of manus of larger 

 cheliped of largest specimen 24 millims., of palmar portion 14, 

 of carpus 3, of merus 11 ; of manus of smaller cheliped 15, 

 of carpus 8'5, of merus 8*5 ; width of manus of larger cheli- 

 ped 10. 



ASTACIDBA. 



Panulirus interruptus^ Bandall. 



This is the "lobster" of the San-Francisco market. Large 

 numbers are caught at Santa Barbara and other points south 

 of San Francisco. 



Stimpson states that it inhabits rocky ledges in rather deep 

 water.
