Telson with a very small apical notch, lateral margins very slightly 
concave, 2 apical spines on each apex. 
First antenna reaching nearly to apex of peduncle of 2nd antenna, 
3rd joint a trifle shorter than 2nd, Ist a little shorter than 3rd, 
flagellum not quite as long as peduncle, 7-jointed. 
Second antenna not half length of body, ultimate and penultimate 
joimts subequal, flagellum a little longer than peduncle, 16-jointed. 
First gnathopod ¢, 4th joint with a rounded pellucid lobe, 5th 
prominently lobed, 6th shorter and narrower than 5th, at least 
24 times as long as greatest width, widening slightly towards lower 
apex where it is scabrous and pellucid and produced beyond the short 
transverse palm as a short rounded lobe, palm with a few setae, finger 
matching palm. 
Second gnathopod ¢, imner anterior margin of 2nd joint with a 
well-marked, straight, apically rounded keel, outer front apex has a 
smaller lobe, 3rd with a strong pellucid lobe on anterior margin, 6th 
ovate, widest in the middle, palm oblique, spinose, with a fairly deep 
but small notch near hinge, and a shallow one near the undefined 
junction of palm and hind margin, finger overlapping palm and 
tapering to a fine point, inner margin sinuous. 
First and second peraeopods not strongly spinous or setose, 4th-6th 
joints spinose on both margins, finger with a very minute setule. 
Third to fifth peraeopods, 2nd joint increasingly expanded, hind 
margin nearly straight, with setiferous serrations, strongest on 5th 
peraeopod, postero-inferior angles rounded, in 5th peraeopod reaching 
to end of 38rd joint, 4th to 6th joints spinulose on both margins, finger 
with minute setule, all three peraeopods more slender than in the 
previous species. 
First uropod with marginal spines only on inner ramus. 
Second uropod with marginal spines on both rami. 
Third uropod, peduncle with 2-3 apical spines, ramus a trifle longer 
than peduncle, slender, with 3-4 apical setae. 
Length: 12 mm. 
Colour: In spirit, whitish, eyes black.

The specimens which Krauss assigned to Orchestia hottae M. Edw. 
may perhaps be referable to this species, though I have not seen 
Krauss’ specimens. The description of the 2nd gnathopod of O, 
bottae as given by Stebbing in Das Tierreich applies very well to that 
of the present species.
