rudimentary and the three to the rear are behind the 5 ventral 

 teeth which cover the same space as 6 of the dorsal. Each of 

 the pleon segments from the third to the sixth is extended 

 about equally in the medio-dorsal line over the segment 

 behind it ; the sixth is as long as the telson. The latter on its 

 narrow distal half has 4 pairs of spines, and on the narrow 

 apex 3 small and 2 moderately large spines. Bate's much 

 larger specimen of A. sica has 9 or 10 pairs of dorso-lateral 

 spines on the telson, and the scale of the second antennae, 

 according to Kemp as well as Bate, is regularly narrowed to a 

 . sharp point armed with an apical spine. In the present 

 specimen the apical spine is distinct enough, but it overtops 

 an apical border which is almost straightly truncate and broad 

 enough to carry 9 little slightly overlapping lobes. Unfortu- 

 nately all the setae are missing from this appendage. The 

 mandibular palp is described and figured by Bate as two- 

 jointed, but it appears to be undoubtedly three-jointed, as 

 figured by S. I. Smith in 1882; the first joint and the setose 

 third being each shorter than the second. The specimen had 

 only two of its peraeopods remaining, a first and a fifth, the 

 latter almost devoid of setae, but this bareness might be 

 accidental. Length 46 mm., carapace 15 mm., of which the 

 rostrum accounted for 7 mm. The telson was 6-5 mm. in 

 length, the scale of the second antennae 6 mm. The outer 

 branch of the uropods is considerably longer than the inner, 

 the tooth of its outer margin at some distance from the 

 rounded apex.
