Cephalic region. — Head wide, trapezoidal, hardly narrowed 

 posteriorly, with cephalic lobes small and short, not extending the le- 

 vel of the front; this latter slightly convex, angle-shaped prominent; 

 ocular tubercle black, widely elliptical, very small, equalling in width 

 about onefifth the width of the front; the distance between the eyes 

 a little less than the diameter of the eye; the upperside of the head-plate 

 along the frontal edge and at the sides of the ocular tubercle covered 

 with brown bristles, thickened at base and distinctly curved inwards 

 and forwards. 



Mandibles hardly inflated at base, gradually narrowed forwards 

 into straight elongate fangs, covered above with bristles and spines; the 

 immovable fang a little longer than onethird of the length of mandible 

 and furnished on the outer row with eight or eleven small teeth; bet- 

 ween the third and fifth teeth only one intermediate tooth is situated, 

 with a distinct space behind it. Flagellum short, with a short stalk or 

 peduncle, which is almost twice as short as the scapus; this latter 

 almost symmetrical, lancet-shaped, with a short apex, at base gradually 

 narrowed into a slightly thickened, short and straight peduncle; at 

 base of flagellum, behind it, 

 a single straight spine is fixed, 

 directed forwards and hardly 

 extending with its apex to the 

 base of flagellum. 



С t e n i d i a of a very 

 remarkable form: short, very 

 wide,shovelshaped, with a very 

 short stalk; each ctenidium 

 furnished distally with a little 

 helm bearing curved apex; ctenidia fixed along the hinder edge of 

 the fifth abdominal sternite, in one row, composed of five ctenidiB 

 on each side at the middle line of abdomen; colour of the ctenidia 

 dully brown, with the stalk pale and helm almost white. 



Palpi and legs rather long and moderately thickened; femur 

 of the palp on its underside with long pale brown bristles, irregulary 

 situated only on the distal half of this joint; tibia bearing below a 

 number of long bristles, resembling the former, but situated in three 

 longitudinal rows; metatarsus distally hardly narrowed, nearly parallel- 

 sided, slightly depressed, with a row of stout spines on each side 

 below; between these spines on the under surface of the joint only a 

 few bacilliform bristles are situated, not shorter than the spines; tarsal 

 joint of the palp short, conical. Tarsus of the first pair of legs almost 

 cylindrical, with a pair of very small, but distinctly developed claws; 

 the spines situated on the joints of legs as follows:
