No. 38, sent by Dr. Gilchrist, from "Eight Whale" in 

 False Bay. This species has the branchial cylinders single, 

 not very long, with small double accessory appendages in the

No. 2, specimens sent by Dr. Gilchrist, "from skin of a 

 Balsenoptera [q. Megaptera] (humpback whale)," appear to 

 agree with Liitken's account of this species, from which he at 

 one time hesitatingly distinguished C. pacificus.

Consistency requires that this tribe should be named 

 Phronimidea, from Phronima, the oldest of its genera.
