'Lu bul hollowed out in the middle; ii i across over more than 



thirds "i tl litulum, beyond the middle ol the basal segment of the scutum. 



1', idrical, ilightly longer than half the length of the capitulum,

studded with Mum beads of chitin externall) and shows, in old specimens, scale-like exeri 



with them. Delicate hairs are planted on tin- blunt beads of the surface; they 



more conspicuous in young specimens than in the full-grown. In the very old 



s from the Kei [slands the surface of the peduncle, like that <>f the capitulum, has a 



oating. 



I in- largest specimen had a capitulum ut' 7,5 mm., most individuals however, are 



r than 4 mm. and a good many of the specimens art: still smaller. The capitulum ol 



figured, fig. 2d. only measured 2 mm., that of (114. 1, o mm. 



Mouth. Lalirum bullate, with smal! palpi bearing numerous bristles, some of them 



at the apex. Teeth about t8, bead-like distally, triangular and close to one another 



in the middle. 



Mandibles (fig. 6) narrow, with tour teeth and the inferior angle formed by a group 

 of very small teeth: teeth 2, 3 and 4 bearing an additional tooth near the extremity. 



Maxillae (fig. 7) with a notch beneath the three upper spines, one of which is much 

 stronger and mie much shorter than the third. In the notch which is wide but not very deep 

 four slender spines are planted, and the projecting part beneath the notch bears about si 

 moderately strong spines and a few hairs. 



I irri. First pair much shorter than and far removed from the second pair: seven 



lents in the longer and six in the shorter ramus. The shape of the segments is nearly 



quadrilateral, with the exception of the first segmenl which is of an elongated quadrangular form. 



Nearly the whole surface of the segments is clothed with spines, which grow longer and stronger 



towards the terminal segments. The second-sixth pair of cirri have both rami of equal length. 



The segments are rather long and bear as a rule four or five pair of spines on the anterior 



side and a tuft of small spines on the posterior near the junction of two segments. A few very 



icate spincs are scattered over the surface of each segment. 



Caudal appendages narrow, thin, more than half as long as the pedicels of the 

 sixth cirrus: a tuit of bristles, two or three of which are much longer than the others, is placed 

 on die summit; no bristles or one isolated bristle on the sides. 



1' i-nis short, thick, terminating in a conical part bearing a tuft of extremely delicate 

 - at its extremity. 



General remarks. This species shows a certain resemblance to /). Warwicki\ the 



ever, being numerous and, so far as 1 could make out, constant, there can be 



little doubt but that the) represent different species. As in D. Warwicki the scutum and tergum 



ol y are different from the same valves in older specimens: the shape of these
