LITHODES CALIFORNIENSIS, dcw species. 



This species is remarkably like the preceding-, excei)t in tlie relative 

 length of its spines and the form of the rostrnm. It comes from about 

 100 miles farther south. There are two specimens, both females, while 

 the only representative of the preceding species is a male. As the 

 differences between them are not known to be sexual, I hesitate to unite 

 them. 



The spines of the carapace are much shorter and stouter, but occupy 

 the same relative position. On the lateral margin there are two long 

 spines; the one above the third ambulatory foot equals in length, but 

 is much stouter, than the one similarly placed on the preceding species. 

 The most marked difference between the two species is in the rostrum; 

 in both specimens of L. C((lifoniien.sis the rostrum is bifid, while in L. 

 rathbuni it is bifurcate, the tip being composed of two well-developed 

 divergent horns. The subrostral spine extends out almost as far as 

 the rostrum proper. The chelii)eds are as in L. rathhuiii, except that 

 the spines are shorter and there is less gape in the right hand and more 

 in the left.

The measurements and description of L. s^nnosisslmHs given by 

 Brandt indicate that the thorax sent him by Wosnessenski was that 

 of a young specimen of Lithodes. The Alaskan collections contain many 

 young Lithodes that come well under Brandt's short description, except 

 that the rostrum proper is bifid, while Brandt describes it as simple. 

 One specimen from a lot taken at station 3233, 7:^ fathoms, Bristol 

 Bay, answers his description in this respect. I believe this specimen 

 to be abnormal, as the other young from the same station have the bifid 

 rostrum. The spines on the carapace of the young are placed as in the 

 adult, but are proportionally juuch longer. A large amount of dredg- 

 ing has been done in Alaskan waters, and nothing that I have seen 

 approaches the description of L. spinosissimus except the youug Lithodes 

 which 1 have confidently referred to L. eamtschaticus.
