that of the 2 posterior pairs, however, much reduced in size, and consisting of 

 only a single joint tipped with 2 subequal setse. Last pair of legs more pronoun- 

 cedly foliaceous than in the type species, distal joint regularly oblong oval in form, 

 and provided with 5 rather small setse, the 2 apical ones very unequal in length; 

 inner expansion of proximal joint conically produced, and extending about to the 

 middle of the distal joint, tip narrowly truncated and carrying 2 slender subequal 

 setse. Ovisacs well defined, but as in the preceding species, closely juxtaposed. 



Colour dark grey. 



Length of adult female 0.60 mm. 



Remarks. This form, first described by Th. Scott as a species of the 

 genus Cletodes, is easily distinguished from the preceding species by the broader 

 rostral projection, the acutely produced lateral parts of the caudal segments, and 

 the shorter and broader caudal rami. In the structure of the appendages also, 

 some well-marked differences are found, as indicated in the above diagnosis. 



Occurrence. I have found this form occasionally at Farsund, south coast 

 of Norway, in a depth of about 20 fathoms, muddy sand; and Th. Scott also 

 records it from the Finmark coast. 



Distribution. Scottish coast (Scott).

Specific Characters. Female. Body somewhat more slender than in the 

 2 preceding species, with the posterior division less broad. Cephalic segment 

 about the length of the 3 succeeding segments combined, rostral projection short 

 and broad, blunted at the tip. Urosome with the anterior segments densely spi- 

 nulose at the hind edge, their lateral parts however not acutely produced; last 

 segment, as usual very large, with the anal opercle minutely denticulate. Caudal 

 rami narrower and more produced than in E. latus, tapering considerably dis- 

 tally, dorsal seta issuing close to the base, middle apical seta slender and almost 

 as long as the urosome. Anterior antennae resembling in structure those in E. 

 latus. Posterior antennae likewise rather similar, though comparatively larger. 

 Posterior maxillipeds rather stout, with the hand oval in form and densely cili- 

 ated inside. 1st pair of legs comparatively larger than in E. latus, and having the 

 terminal joint of the outer ramus armed with 3 curved spines and 2 setse; inner 

 ramus extending to the end of the middle joint of the outer, and having the middle
