armed with two small teeth near the joint, while the corre- 

 sponding edge of the finger is nearly straight and armed with 

 a single, tooth near the joint. The large plug-like tooth 

 usually present on the ringers of shallow-water forms is 

 wholly absent.

"With some doubt we identify with this species three 

 specimens — one perfect with the exception of the fourth and 

 fifth pairs of legs, which are absent, the other two con- 

 siderably broken, trawled at Station 233, 185 fathoms. They 

 only differ from the figure in possessing three instead of two 

 teeth on the dorsal margin of the rostrum. The position of 

 these three teeth differs in the three specimens, although 

 occupying much the same space as the two teeth of the type. 

 In all other respects our specimens appear to be the same as 

 the type.

Three specimens were obtained at Station 233, 185 fathoms, 

 and differ from the figure of the species in the Rec. Fig. Crust. 

 in the following points: — the rostrum, in our one unbroken 

 specimen, is armed with four teeth only on its lower margin ; 

 there is a small sharp ocular spine; the dorsal carina behind 

 the orbital margin bears five teeth in two, four teeth in one 

 specimen ; the postero-inferior angle of the fifth abdominal 

 pleura is pointed and sharp, not rounded ; the sixth abdo- 

 minal pleura is produced postero-inferiorly into a small sharp 

 tooth, not rounded ; the telson bears at its extremity, in 

 addition to the sharp central tooth, a pair of lateral movable 

 spines, and between these and the central tooth bunches of 

 long stiff hairs.
