GAMMARIDEAN AMPHIPODA 141 



that from Japan, which is straight. The anteroventral corner of coxa 

 1 is sharper than tliat shown by J. L. Barnard (1964d) and that of 

 Stebbing (1888) in his view of the flattened appendage. 



The lower lip is illustrated herein to demonstrate the occurrence of 

 weakly developed inner lobes, which Stebbing shows in slightly dif- 

 ferent form and wliich are even more weakly developed in J. L. Bar- 

 nard's (196id) specimens from Japan. The small accessory flagellum 

 is also enlarged in the drawings.

This remarkable species has been recorded only once heretofore, 

 from a specimen 30 mm long collected at a depth of approximately 

 3700 m, west of Peru on a track between the Galapagos Islands and 

 Easter Island. Two specimens at hand, from southern Baja Califor- 

 nia in depths of about 3500 m, differ in a few details from the descrip- 

 tion and figures of Schellenberg. Some of these differences may be 

 the result of differing techniques in illustrating; possibly Schellen- 

 berg's illustrator (C. Gomansky) made the drawings freehand; for 

 instance, coxa 4 differs in Schellenberg's plate 1 from the in toto draw- 

 ing to the dissected drawing. In the figures presented herein the coxae 

 of the in toto drawing are illustrated in their flattened conditions and 

 coxa 4 resembles that shown by Schellenberg on his in toto drawing 

 but not on his presumed flattened view. Coxa 1 and its relationship to 

 pereonite 1 differ strongly in the present specimens, coxa 1 being nar- 

 rower and attached by a straight juncture to pereonite 1 ; Schellenberg 

 shows it as much broader and attached to a strongly rounded ventral 

 edge of pereonite 1. Even more remarkable are the disproportion- 

 ately long pereopods 3 and 4 of the present material in comparison to 

 those of Schellenberg, but this phenomenon is characteristic in allo- 

 patric populations of numerous species of Amphipoda.
