210 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
immediately behind the cervical suture. The posterior margin 
of the cephalothorax is nearly as broad as the distance between 
the first antero-lateral teeth. 
The triangular epistome or interantennular space is in contact 
with the front. The slightly convex subhepatic and the ptery- 
gostomian regions are smooth and unarmed, but a small, subacute 
tooth occurs at the external angle of the anterior margin of the 
buceal cavity. The male abdomen is quite similar to that of 
D. caput-mortuum ; the terminal joint is exactly once and a half 
as long as the penultimate, and the posterior margin of the 
peuultimate joint measures twice the length of this joint. 
The legs closely resemble those of D. caput-mortuwm. The cheli- 
pedes are equalandsmooth. The upper margin of the arm bears 
a row of five, small, equal, obtuse teeth or tubercles, and similar 
small tubercles are found on the two other margins. The three 
surfaces of the arm are smooth. The upper surface of the wrist 
is smooth; as in D. caput-mortuum, the anterior margin of the 
upper surface, which articulates with the hand, is raised on either 
side into an obtuse prominence, and the distal half of the inner 
margin is armed with four small obtuse teeth, which gradually 
increase a little in size, so that the distal one is the largest. 
The hands resemble those of D. caput-mortuum. Their outer and 
inner surfaces are smooth, but the upper margin of the palm is 
armed with two or three small, obtuse teeth. The calcareous 
fingers are of a beautiful rose-colour, and when closed meet 
together along their whole length; they are strongly toothed, 
the inner edge of the mobile finger with five, that of the immobile 
finger with four teeth, and the teeth of the index are slightly larger 
than those of the mobile finger. | | 
The surfaces of the other legs are also smooth, and nowhere 
present nodosities or tubercles. The second and third pairs of 
legs are about of the same length, and almost as long, as the 
chelipedes; the fourth pair are only half as long, and the last 
pair are somewhat shorter and smaller than the legs of the second 
pair. Avs already observed, the entire animal, with the exception 
of the fingers of the anterior legs, which are smooth and glabrous, 
is everywhere covered with a close velvety pubescence. 
Although I have not been able to study the female, I refer this 
species to the subgenus Dromidia, on account of its ridged endo- 
stome, and because it completely agrees in its generic characters 
with D. unidentata, Rupp., which is undoubtedly a true Dromidia.
