80 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 8 



Remarks. — The species seems to be common in the Gulf of Cali- 

 fornia and along the west coast of Mexico and Central America. A single 

 record exists from Peru, possibly an error in labeling. Its soft skin, bushy 

 tentacles, and usually dark coloration make it easy to recognize. In life 

 it is often bright red ; in alcohol it fades to white with dark tentacles. 



The name calif ornica has unfortunately been applied to the common 

 frondosa-Wke form from Bering Sea, C. fallax Ludwig. During the 

 Albatross expeditions a single specimen of this Arctic form evidently got 

 mixed up with some material from the Galapagos Islands ; Edwards, 

 who worked over the material, gave the name calif ornica to this specimen 

 with the dubious locality, as well as to the larger individuals of C. fallax 

 from Bering Sea (while the smaller individuals were identified as C. 

 fallax). The supposedly Galapagos specimen, which shows strong signs 

 of having been dried up, is a typical huge, brownish, frondosa-like form 

 and cannot be separated from the individuals of C. fallax of the same 

 size collected in the Bering Sea.^ Cuctimaria californica, on the other 

 hand, is much smaller and either completely slate gray or black, or the 

 tentacles and part of the anterior end are dark colored. Its spicules are 

 entirely different from those found in C. fallax.

Diagnosis. — Medium-sized form. Feet restricted to ambulacra, re- 

 tractile. Tentacles not bushy, filled with spicules, the 2 ventral ones small. 

 Calcareous ring simple; other anatomical features apparently typical of 

 the genus. 



Spicules 4-holed buttons and smooth to knobbed plates. Feet with 

 rudimentary end plate and numerous slender supporting rods, slightly 

 shorter in the dorsal appendages. Introvert and tentacles with large per- 

 forated plates and rods. Color yellow, with or without irregular spots, 

 or mottled gray and brown. 



Holotype. — Hamburg Museum. 



Type locality. — Chile. 



Distribution. — Various localities in Chile.
