1st pair of legs with the outer ramus about the length of the 1st joint of the 

 inner, last joint a little longer than the 2nd and armed with 3 claw-like spines 

 and 2 geniculate setse; inner ramus with the 1st joint about twice the length of 

 the other 2 combined, seta of the inner edge somewhat remote from the apex, 

 last joint longer than the 2nd, and armed at the tip with a very slender claw 

 and 2 unequal setse. Last pair of legs with the distal joint oblong conical in 

 form and obliquely truncated at the tip, both edges densely ciliated; inner ex- 

 pansion of proximal joint scarcely extending to the middle of the distal joint, and 

 armed with 4 strong spiniform seta?, the outermost but one much the longest. 



Colour dark yellow. 



Length of adult female 0.63 mm. 



Remarks. The present species seems to be that described by Brady in 

 his monograph as Ameira longipes Boeck. It is quite certainly very different 

 from the form so named by Boeck, of which a description has been given above. 

 The form recorded by Brady as the male does not belong to the species de- 

 scribed, but more properly to a species of Amphiascus, as clearly shown by the 

 prominent rostrum and the transformed inner ramus of the 3rd pair of legs. 



Occurrence. I have met with this species occasionally off the south coast 

 of Norway, at Ris0r, Lillesand and Farsund, in moderate depths, among algas. 

 In the living animal no distinctly defined eye could be detected, but only some 

 irregularly disposed dark pigmentary patches occupying its place. 



Distribution. British Isles (Brady). 



145. Ameiropsis longicornis, G. 0. Sars, n. sp. 



(PI. CXLIX). 



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

 preceding species, with the anterior division scarcely longer than the posterior. 

 Cephalic segment about the length of the 3 succeeding segments combined and 

 rather deep, rostral projection very small. Last caudal segment shorter than the 

 preceding one. Caudal rami broader than they are long and transversely trun- 

 cated at the tip. Eye in living specimen distinctly perceptible and of light red 

 colour. Anterior antennae much more elongated than in the preceding species, 

 exceeding even in length the cephalic segment, proximal part considerably more 

 than twice as long as the terminal one. Outer ramus of posterior antennae with 

 the proximal joint narrow fusiform in shape and edged inside with small spinules, 

 terminal joint very small, with the 2 apical seta3 of equal size. 1st pair of legs
