NO. 4 SCHULTZ: ISOPODA 15 



narrower after the seventh peraeonal segment. Coxal plates present on 

 segments two to seven (only four to seven visible in dorsal view). 

 Coxal plates more acutely pointed and extended farther backward in the 

 more posterior segments. The coxal plate extensions of segment seven 

 enclose first pleonal segment within their lengths. Five pleonal seg- 

 ments distinct with lateral edges of first four visible. Lateral edges of 

 pleonal segment five enclosed under largest pleonal segment four. Lat- 

 eral extensions of pleonal segments not recurved. Telson pointed with 

 serrated lateral margins. Uropodal base with produced medial margin; 

 exopod and endopod both pointed with spines and plumose setae along the 

 serrated margins. All peraeopods ambulatory although last four are 

 laterally compressed with long plumose setae orginating on margin of 

 basis; setae about as long as basis is wide. Many large plumose setae 

 also originate on distal end of basis extending to middle of propodus. 

 All other segments with some setae; dactylus minute. Antennae one 

 with nine flagellar articles; antennae two with about 16 articles. Maxil- 

 lipedal palp with three segments, endite very small. Mandible with 

 toothed incisor, large lacinia mobilis, large toothed mandibular proc- 

 ess. Palp with three articles, last two with many setae. 



Measurements: Holotype female 8.0 mm long. 



Type locality: 6851; Coronado Canyon; 812 m; Feb. 1, 1960; 

 green mud. Lat. 32° 37' 54"xN, Long. 118° 55' 40"W. 



Materials studied: 6833 ( 3 ) ; 685 1(1). 



Distribution: The species was taken in Tanner Canyon (at 813 m) 

 and in Coronado Canyon from green muddy sand and green mud. 



Affinities: The species differs from Cirolana cubensis Hay (Richard- 

 son, 1905), another blind species, in that its fourth pleonal segment is 

 much wider and the apex of the telson is pointed. It is most like C. 

 gracilis Hansen (Richardson, 1905), but C. gracilis has more definite 

 peraeonal coxal plates and is not blind.

Diagnosis: Red eyes of moderate size. General body shape ovoid 

 with truncate posterior margin. All body segments distinct and, with ex- 

 ception of pleonal segment one, with pointed posterolateral edges. Per- 

 aeonal segments two to seven with distinct coxal plates. Coxal plates 

 forming lateral extensions, each anterior one extending laterally more 

 than that of the preceding segment and continuous in general body out- 

 line with the recurved pleonal segment extensions. Pleonal segment five
