74 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
Seven rather young specimens (6¢,19) were collected at 
Owen Island, the largest of which is 27 millim. broad and 16 
millim. long. 
It is very difficult to distinguish young specimens of this species 
from the young of the closely allied Thalamita admete, Herbst, 
as the principal characters by which they are distinguished 
from one another appear successively during growth. One of 
the chief characters is the more pronounced granulation of the 
carapace and of the chelipedes. The largest specimen already 
presents many characters proper to Thal. Savignyi, though 
not all. The upper surface of the cephalothorax is hairy, and 
the minutely granulated transverse lines are very prominent. 
The outer surface of the wrist of the anterior legs is armed with 
three spines (two in 7’. admete) and with elevated lines, between 
which it is hairy and granular. The outer surface of the hands 
bears two granulated crests, and between the lower crest and the 
upper margin the surface appears already granular and hairy ; 
the rounded under margin of the hands is equally granular. 
The whole inner surface of the hands, on the contrary, and the 
elevated ridge near the lower margin, which proceeds along the 
immobile finger, are smooth, as in 7’. admete. 
In the younger individuals this granulation is still less pro- 
nounced, so that it becomes very difficult to distinguish them 
from Thal. admete. 
I may finally add that a young female, the cephalothorax of 
which is only 153 millim. broad, is already provided with eggs. 
Thal. Savignyi, however, attains a breadth of 40 millim. 
Thalamita Savignyi was first discovered in the Red Sea, but 
has since been recorded from New Caledonia by Milne-Edwards ; 
the species has evidently a wide distribution. According to 
Heller, Thal. admete occurs at the Nicobar Islands. 
50. THALAMITA INTEGRA, Dana. 
Thalamita integra, Dana, United States Explor. Expedition, Crustacea, 
part i. p. 281, pl. xvii. fig. 6; Alph. Milne-Edwards, I. ec. p. 358. 
One young male was found at Elphinstone Island. This 
specimen, the carapace of which is only 153 millim. broad and 
10 millim. long, wholly agrees with the description published by 
Alph. Milne-Edwards. 
Thalamita integra has been recorded from many islands of the 
Pacific Ocean by Dana, and from Mozambique by Hilgendorf.
