inner portion of the basal joint scarcely produced and 

 furnished with one very small and three moderately long 

 and plumose setae (PI. XVII. fig. 9). The secondary joint 

 is broadly ovate, being about one third longer than broad, 

 and widest near the proximal end ; the apex is obliquely 

 truncated and provided with one small and four moderately 

 elongated seta*, as shown by the drawing.

The only specimens were obtained in a gathering from 

 Padstow, Cornwall, collected in May 1903. Dr. Brady 

 records this species from the Scilly Islands. Though this is 

 comparatively a small form, it is readily distinguished by 

 the form of the second maxillipeds.

A number of specimens were obtained which appear to 

 belong to H. uniremis of Kroyer. The antennules of this 

 form, as in the last, are composed of nine joints. The primary 

 joints of the filth thoracic feet of the female are broadly 

 foliaceous, and the inner portion which reaches to near the 

 middle of the secondary joint bears four stout spinii'orm setse 

 on its broadly but irregularly rounded extremity. The 

 secondary joint is broadly triangular, and is furnished v\ith 

 five stout setse, one near the distal end of the inner margin, 

 two at the apex, and two on the outer margin, as shown in 

 the drawing (PI. XVIII. fig. 8). The whole armature of 

 the fifth pair is coarsely setose.
