eral stages, they make their way to the outside, where they may be 

 found with those with 3 pairs of ambulatory legs, up to the adults that 

 were sexually mature. At various times immature forms and adults were 

 found on Coryo?norpha, but I have not as yet direct evidence of their 

 living on these palm hydroids in the youngest stages as they were in 

 Tubularia. 



This species has been found during a number of years at Balboa, 

 California. Hundreds of specimens have been obtained from Newport to 

 San Diego, California. 



The total body length of an average specimen was 2.5; total leg 

 length, 7; spread, 15. 



One young specimen, Station 532-36, San Francisquito Bay, Lower 

 California, March 2, 1936, 20 fms. 



Also 1 specimen, Station 1 162-40, off Seal Beach, July 23, 1940, 95 

 fms. 



One specimen. Station 978-39, Santa Barbara Island, east of Gull 

 Island, May 28, 1939, 21-28 fms.

Diagnosis: Body and legs rather heavy skin, pitted. Transverse 



processes separate, but not widely separated, almost touching. Second 



coxal joint larger at its distal end, with a marked projection on one side. 



Second tarsal joint heavy, arched, bearing 2 prominent teeth at its base. 



Description 



Body: Rather short; lateral processes about as long as their own 

 diameter, with bases contiguous. First 2 intersegmental lines hardly evi- 

 dent. The 2 forward processes point forward slightly. The 2 caudal proc- 

 esses point more decidedly backward. 



Eye tubercles: A large conical projection arises from the anterior 

 edge of the body and projects over the proboscis. The eyes are not very 

 evident. Deeply pitted skin. 



Proboscis: Cylindrical, with end rounded. Almost as long as the 

 body. Diameter ^^ its length.
