rather strong apical seta and 2 lateral ones, the distal of which is very small. 

 Posterior maxillipeds of moderate size. 1st pair of legs with the inner ramus 

 extending somewhat beyond the outer, its joints successively diminishing in length, 

 the 1st one oblong in form and, like the other 2, carrying inside near the end 

 a ciliated seta, last joint moreover armed at the tip with a claw-like spine and a 

 slender seta. The 3 succeeding pairs of legs with the inner ramus scarcely more 

 than half as long as the outer, its 1st joint of normal appearance, and the last shorter 

 than the middle one and only provided with a single seta inside, terminal joint 

 of outer ramus in 2nd and 3rd pairs likewise with a single seta on the inner 

 edge, in 4th pair with 2 setae, the distal one very strong and denticulated along 

 the edge. Last pair of legs with the distal joint obliquely oval in form and less 

 perfectly defined at the base, marginal seta? only 4 in number, the outer 2 

 rather strong, inner edge of the joint straight and quite smooth; inner expansion 

 of proximal joint linguiform in shape, and extending as far as the distal joint, 

 marginal setse 4 in number, all issuing from the obtusely rounded extremity, the 

 outermost but one much elongated. 



Colour not yet ascertained. 



Length of adult female 0.52 mm. 



Remarks. The above-described form is evidently identical with that 

 figured (but not described) by Th. Scott in the above-quoted journal as Ameira 

 reflexa var. It is however quite certainly specifically distinct from the form 

 previously discribed by that author as Ameira reflexa, which seems more properly 

 to be referable to the genus Parameira. The specific name here proposed refers 

 to the peculiar inflated shape of the last joint of the anterior antennse. 



Occurrence. Only a solitary female specimen of this form has hitherto 

 come under my notice. It was found in a sample taken last summer at Kors- 

 havn from a depth of about 20 fathoms, sandy bottom. 



Distribution. Scottish coast (Scott). 



Pseudameira furcata, G. 0. Sars, n sp. 



(Suppl. PI. 30). 



Specific Characters. Female. General form of body resembling that 

 in the preceding species, though perhaps still shorter and stouter. Rostral 

 projection a little more prominent than in that species and acutely pointed. 

 Urosome about the length of the anterior division and distinctly narrower; genital 

 segment very large, fully equalling in length the other 3 segments combined. 

 Caudal rami considerably produced, being about as long as the last 2 segments 

 combined, and narrow linear in form, apical setae rather strong and conspicu-
