ipitulum much compressed with the apex highly produced. Scuta with the l>asal segment 

 triangular and the occludent segment broad, having the shape • ■! > calpel; terga with the lower 

 about as wride as the occludent segment of the scuta; carina much bowed, terminating in

 meml ing the valves with rather long hairs. 



rhe occludent segment is long, flat, pointed at its extremity; its 

 occludent margin is straight, the carina! margin convex, whence the shape <>i' tin- segment is 

 tliat calpel. The basal segment is triangular, small; only a small part <»i the valvi

 might be called the junction of the two segments is caleified, but hm calcification is 

 in tli" basal segment itself. 



I erga tfig. 10). Scutal margin excised at a point vis a vis the apex of the scutum; 

 the excision separates a smaller occludent projection trom a larger carinal projection or lower 

 part. < )ccludent margin simply and slightly curved. Incipient calcification ai the umbo, where 

 the valve shows an indistinct third prominence. 



I arina (fig. i i . Much bowed, narrow, long. The basal end is rectangularly inflected 



and stretches internally to about the half of the diameter of the peduncle. The whole valve is 



caleified; the basal portion is slightly wider than the upper part and is excised ai its extremity. 



Peduncle narrow. especially close under the capitulum; about " K the length of 



the capitulum. 



Si /e. Very small, the capitulum measuring not quite 2 mm. in length. 

 Mouth. Lal» rum bullate. Mandibles (fig. 12) with tour teeth and the inferior 

 angle tooth-like and acuminated. Maxillae (fig. 13), with three larger spines at the upper 

 angle, beneath which there is a triangular incision or notch, bearing two slender hairs. The 

 edge beneath this notch is straight and projecting, and hears six or seven unequal hut rat lo r 

 large spin< 



t irri. First pair short with the rami very unequal: the longest lias five, the shortest 

 four segments; the segments are nearly quadrangular with the exception of the first which is 

 elongated; terminal segments sm;dl and blunt. Segments not thickly clothed with hairs or bristles; 

 these are placed somewhat irregularly. 



The other cirri have ver) long and slender segments, bearing three pairs of spines

The caudal appendages are extremely slender hut not longer than half the length 



ot tl ! ^ of the sixth cirrus. They bear a few (about four) very delicate hairs at theirends. 



Th' ecimens are attached to long. yellowish-brown hairs or spines, which are hollow 



angular pointed teeth placed in irregular rows. They wen- taken, October 1899,
