and the four anterior segments of the pereion. Flagellum 
about the same length as the peduncle. Secondary appendage 
small. The inferior antenne are a little longer than the supe- 
rior, the peduncle being about three-fourths of the antenne. 
The first pair of gnathopoda are cylindrical, having the poste- 
rior margin of the carpus and propodos thickly ciliated ; 
carpus as long as the propodos, tapering; dactylos apical, 
straight. ‘The second pair of gnathopoda are long; propodos 
ovate; palm oblique, defined by a strong tooth, armed near the 
base of the dactylos with a double dentated tubercle, and 
near the middle with three teeth, of which the anterior is the 
largest; dactylos short, shorter than the palm, curved and 
simple. The three posterior pairs of pereiopoda have the 
basos narrow and the entire appendage increasing posteriorly 
in length; the posterior pair of p!eopoda having the ramus 
nearly three times as long as the peduncle. The telson is 
tipped with strong cilia. 
This species was first taken and described by the Rev. 
A. M. Norman, from a single specimen dredged in deep water 
off Holy Island. We have since received it, through Mr. 
Dawson, from the coast of Aberdeenshire.
