Nyctiphanes Couchii is quite distinct from N. norvegica, 

 and specimens from all the above sources agree in the charac- 

 ters I here give to distinguish it from the latter species. 



Nyctiphanes norvegica. — A spine on each side of the cara- 

 pace behind the middle. Rostrum scarcely developed, so 

 short as to leave the base of the eye-stalks exposed. Lobes 

 of carapace over the eyes drawn out into slender spine-like 

 points, these points projected as far as, or further forward 

 than, the rostral lobe. No spine over the base of the telson. 



Nyctiphanes Couchii. — A much smaller and more delicate 

 species, usual length about 13 millim. No lateral spines on 

 carapace. Rostrum more developed than in norvegica, in 

 shape broadly and bluntly triangular, concealing the base of 

 the eye-stalks ; lobes of carapace over the eyes not produced. 

 A spine over the base of the telson as well as a small ventral 

 })roanal spine. In the male, of which some examples occurred 

 at l^anff, the antennules, in addition to the usual retlexed 

 membranous leaflet of the first joint, have another reHexed 

 membranous leallct at the end oi the second joint of the
