212 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 18 



telsonic apices are armed with long setae and not short spines; (4) the 

 inner ramus of uropod 3 is quite short while in P. lucubrans it is nearly 

 as long as the outer ramus; (5) article 2 of. peraeopod 5 is broad distally 

 and truncated while in P. lucubrans it is narrowed and convex distally; 

 (6) the posterior edge of article 2 of peraeopod 5 has only 3 teeth and 

 these are larger than the 6-7 teeth on P. lucubrans; (7) article 5 of 

 gnathopod 1 is very long and slender while in P. lucubrans it is somewhat 

 stouter.

Atypical Specimens (Station 3045-55) 



A female 3 mm in length and bearing brood plates has eyes larger 

 than typical females, more like P. lucubrans, and the uropods are more 

 spinose. However, the specimen is like P. daboius in the, third uropods, 

 the telson and the gnathopods, while article 2 of peraeopod 5 is like 

 P. daboius in that the teeth are smaller. Two juvenile males of this 

 type are present also at the same station and bear eyes with better devel- 

 oped pigment than normally seen in the species. These specimens may 

 be hybrids or mutants. 



Material examined. — 121 specimens at 25 stations. 



Distribution. — Southern California coastal slopes, 42 to 230 fms. 

 A, deep water species which may be an ecophenotype to Paraphoxus 

 epistomus, having reduced eyes. 



Paraphoxus lucubrans, new species 



(Plates 12, 13, 14) 



Diagnosis of female. — Head with rostrum narrowed anterior to 

 eyes but rather short and broad ; eyes medium in size. 



Epistome variable, produced into a small acute cusp or scarcely 

 produced and blunt. 



Maxilliped palp article 4 apex unmodified.
