A single specimen of this genus was dredged in the summer of 1906, 

 and though special effort was made to obtain more, none were found dur- 

 ing either of the following summers. The specimen at hand differs in 

 no essential respect from Holmes's rather full description of P. hemphillii 

 except in the length of the rostrum. This feature is not very definitely 

 stated by Holmes, who says that the rostrum "varies considerably in 

 length, being sometimes broadly and sometimes narrowly triangular." 

 In the figure given by Miss Rathbun the length of the rostrum (meas- 

 ured from the tip to the supra-ocular spine) is about one-fourth of the 

 total length of the carapace, while in the Monterey specimen the rostrum 

 equals about two-fifths of the total length. Miss Rathbun, who has 

 examined the specimen, thought that it might prove a new species, but T 

 hesitate to separate it on the single character of the length of the rostrum 

 without a considerable series for comparison, especially since a speci- 

 men from Catalina Island (the only other Podochela at hand) shows a 

 rostrum in some degree intermediate. Further material may prove it 

 distinct, but for the present it seems best to list it as P. hemphillii, a record 

 which materially increases its range, which as given by Miss Rathbun is 

 "from San Luis Obispo, Cal., to Gulf of California." 



Genus ERILEPTUS Rathbun. 



Erileptus Rathbun, Proc. U. S. Nat. Mus., vol. xvi, 227, 1893 (Type Erileptus
