NO. 3576 AMPELISCIDAE — BARNARD 17 



Records: Oboro Saki; Nagane Saki; and Doumiki Saki, Honshu 

 Island, Japan, 18-61 fms. 



Relationship: Differing from B. rhinoceros Pirlot (1936) to which 

 it is closely related in view of antenna 1, head, telson, uropod 3, 

 pereopod 5 articles 3-7, and uropods 1 and 2, by the slightly more 

 quadriform posterodistal corner of article 2 of pereopod 5, and by the 

 considerably shorter first antenna of the female. In many respects 

 this species also resembles B. crenulata Pirlot (1936) which is close to 

 if not identical with B. daleyi Giles (Pirlot's, 1936, identification of 

 daleyi did not account for the extremely long second article of antenna 

 1), but the head and eyes of B. crenulata differ, the lower lens pointing 

 more ventrally, the anterior edge lacking a small protrusion, and the 

 ventral margin of the head apparently not being strongly excavate 

 for the attachment of antenna 2. Article 2 of antenna 1 is subequal 

 to article 1 in contrast to B. orientalis and the anterior coxae are 

 serrate ventrally. In addition, article 7 of pereopod 5 is much shorter 

 in B. crenulata than it is in B. orientalis. 



The new species is also related to Pirlot's (1936) identification of 

 B. daleyi, but article 2 of antenna 1 is much shorter than in that 

 individual; however, one aberrant specimen of B. orientalis in sample 

 3138 has left and right antennae dissimilar, the left with article 2 

 more than twice as long as article 1, the right with article 2 scarcely 

 longer than article 1. 



This species also resembles a new species to be described by M. 

 Imbach from the South China Sea but differs from it by the sparsity 

 of spines on the "posterior" edge of article 6 on pereopod 3, by the 

 less attenuated and asymmetrical lobe of article 2 on pereopod 5, by 

 the slightly shorter first antennae, the slightly deeper cleft of the 

 telson, the stronger posterior cusp of coxa 4, and the thinness of the 

 setae on the outer ramus of uropod 3. Those two species may be 

 races of a common stem. 



Distribution: Honshu Island, Japan, 33-112 m.

Barnard overlooked the row of spines on article 3 of pereopod 5 in 

 his misidentification of 1960.
