Nyctiphanes Couchit 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 
preanal spine. In the male, of which some examples occurred 
at Banff, the antennules, in addition to the usual reflexed 
membranous leaflet of the first joint, have another reflexed 
membranous leaflet at the end of the second joint of the
