NOTES ON SOME WEST AMERICAN CEPHALOPODS, 



BY S. STILLMAN BERRY. 



As a considerable time has elapsed since the completion of the 

 manuscript for my recent Review of the Cephalopods of Western 

 North America, it is not surprising that several new facts have been 

 brought to notice, while some of those already dwelt upon appear to 

 require reconsideration in the light of recent work by other in- 

 vestigators. Hence the following notes. 



Polypus apollyon Berry 1912. 



It seems fairly doubtful whether all the specimens included with 

 the type of this species in the table of locality data in my report 

 (Berry, 1912a, p. 283) are in reality conspecific with one another 

 or belong to recognizable groups which only a greater abundance 

 of well-preserved adult material than is at present available will 

 enable us to separate. In the meanwhile I am inclined to recognize 

 P. apollyon as distinct from the true P. hongkojigensis Hoyle, 

 a view which, if correct, eliminates the latter species from considera- 

 tion in our fauna.

 ventral line to expose the funnel organ. X 2. [S. S. B. 81.] 



I take this opportunity to give a figure of the funnel organ 

 of one of the specimens from the Coronado Islands in the collection 

 of the University of Cahfornia [S. S. B. 81].
