Some Marine Isopod Crustaceans from off the Southern California Coast 
George A. Schultz 1 
In the summer of 1962 the author identified 
isopods caught in the submarine canyons off the 
southern California coast by workers of the re- 
search vessel "Valero IV” of the Allan Hancock 
Foundation of the University of Southern Cali- 
fornia. The results of that work have been pub- 
lished (Schultz, 1964). There were additional 
isopods collected during the voyage which were 
not part of the canyon fauna and they are con- 
sidered in this paper. The specimens were taken 
from the benthic environment by means of an 
Orange Peel Grab or a Campbell Grab bottom 
sampler. Ten species were taken, 3 of which 
were new to science. 
After the description or mention of each spe- 
cies the station or collection number is given. 
The number in parentheses is the number of 
specimens of the species caught at that station. 
The station numbers referred to are listed in 
Table 1, together with publications where more 
precise information can be found. 
The research for this project was made pos- 
sible by a Teacher’s Research Participation Fel- 
lowship grant by the National Science Founda- 
tion to the Biology Department of the University 
of Southern California. Dr. Robert J. Menzies 
directed the research which was done in the 
Allan Hancock Foundation at the University of 
Southern California. The author wishes to thank 
Dr. Menzies for his part in the work; Dr. Olga 
Hartman, in whose laboratory the work was 
done; Dr. Walter Martin, who administered the 
grant; and the Allan Hancock Foundation, which 
provided the facilities.

DIAGNOSIS: Eyes of two or three ocelli ventro- 
laterally placed near antennal bases and not visi- 
ble in dorsal view, but clearly visible in ventro- 
lateral view. Front of cephalon evenly convex; 
first three peraeonal segments with lateral mar- 
gins not widely separate. Lateral margins of last 
four peraeonal segments separated from first 
three and also from each other by wide gaps. 
Lateral margins of peraeonal segments four to 
seven narrower than those of first three. Coxal 
plates conspicuously visible from dorsal view on 
segments five to seven, very slightly so on seg- 
ments one to four. Pleotelson narrow at base; 
one well-defined pleonal segment present. At 
widest point pleotelson about two-thirds as wide 
as segment seven. Six setae (12 bilaterally) along 
apical margin of telson. Longest peraeopod about 
as long as body, with knoblike merus and many 
spines on other segments. Dactylus on each leg 
elongate with several long, spinelike setae. First 
peraeopod about half length of other peraeo- 
pods; at least three large spines on carpus. First 
and second antennae about same length, both 
about half length of body. First antennal flagel- 
lum with at least four articles; second antennal 
flagellum with five articles; fifth article of second 
antennal flagellum ball-like. Maxillipedal palp of 
five articles, each with at least one large spine; 
two coupling hooks on blade. Mandible with
