the exposed part of the trunk and rather deep, with a strongly marked carina 
running on each side, nearer the dorsal side, from the hindmost part of the 
branchial regions to the base of the pseudorostral projection, the latter rather 
prominent, acute, subrostral corners very small, terminating in a minute denticle. 
Tail (excluding the terminal appendages) shorter than the anterior division. Su¬ 
perior antennae with the peduncle scarcely projecting beyond the tip of the pseu¬ 
dorostral projection, its 2nd joint rounded oval, with 3 blunt serrations of the 
inner edge, last joint extremely small. First pair of legs about the length of the 
carapace, ischial and meral joints forming together a rather short and broad 
triangular piece intercalated between the basal and carpal joints, the latter joint 
very large and broad, forming an oblong quadrangular plate, to the outer corner 
of which the 2 small distal joints are very movably attached. Second pair of 
legs scarcely more than half as long as the 1st, antepenultimate joint rather 
broad, and of same appearance as the preceding one, terminal joint conically 
tapered, with several long bristles at the tip. Uropoda about the length of the 
last 2 caudal segments combined, inner ramus somewhat larger than the outer, 
and almost twice the length of the stem, with only 3 spinules, 2 apical and one 
lateral, inner edge minutely serrate and densely hairy throughout. Colour uni¬ 
formly yellow, without any pigmentary ornament. Length about 4 mm. 
Adult male much more slender than the female, with the anterior divi¬ 
sion less vaidted above. Carapace with an additional carina on each side, 
running parallel to the other and nearer the ventral side; pseudorostral projection 
shorter and blunter than in female. Appendages exhibiting the usual transfor¬ 
mation. Length nearly 5 mm. 
Remarks .—This form was originally described from only 2 specimens, 
both of the female sex, the one not fully developed; and owing to this scantiness 
of material, some errors had been introduced in the original diagnosis. Thus 
the 1st pair of legs are described as only 5-articulate, whereas in reality, they 
are composed of the normal number of joints, 2 of them, however, the ischial 
and meral ones, being so firmly connected as to exhibit the appearance of a 
single joint. The eye, which was stated to be wholly wanting, is in reality 
present in its usual place, though in a rather imperfect condition. Moreover, 
the extremely small and rudimentai’y exopodites on the 3rd and 4th pairs of 
legs were at that time overlooked. The characters of the male, too, could of 
course not be given. 
Occurrence .—The 2 specimens from which the original description was 
made, were taken off the Lofoten Islands in a depth of 50 — 60 fathoms, on a
