The carapace of the largest male specimen measured 29 mm. 
in length by 32 mm. in breadth. The carapace of the female 
measured 20 by 20mm., exactly the dimensions given by 
Studer. 
Locality Cape Point, N.E. by E. ? E., 8 miles; depth, 
g1 fathoms. Bottom, sand and specks. The “ Gazelle” 
specimen was taken in 117 fathoms to the south of the Cape. 
In Studer’s opinion this species belongs to a group con- 
taining Dromidia unidentata (Riippell) and D. rotunda (McLeay). 
With D. unidentata there are no doubt some points of resem- 
blance, but that species has a smooth carapace, with the lateral 
borders almost entire; the chelipeds appear to be similar in 
the two sexes, and the fifth legs are said to be very much 
longer than the fourth, and not so very much shorter than the 
second and third; so that it will not at all suit the definition 
of Exodromia. 
In their work on the Brachyura and Anomura of the 
“Travailleur” and “Talisman” A. Milne-Edwards and 
Bouvier redescribe and figure Bouvier’s Dynomene Filholt. 
They say of this species, “‘ The sexual pleopods of the male 
still bear much resemblance to those of the Homariens, those of 
the second pair are filiform at the extremity and furnished 
at their base with a very distinct exopodite. The following 
three pairs of pleopods are still present at all periods of life ; 
they are biramose and show especially a great relative develop- 
ment in the individuals of medium size, which form almost 
all the gathering made by the “ Talisman.” D. Filholi appears 
to be, so far, the only Dromiacean which presents this character ; 
from this point of view it has remarkably preserved the 
characters of the larvae, and makes a great approximation to 
the Homariens”’ (Op. cit. p. 8, 1900). 
It now appears, therefore, that the Dromiidae have an 
additional link of connection with the Dynomenidae. It 
should, however, be remembered that the details of structure 
in these male pleopods differ considerably. According to 
Alcock, the rudimentary pleopods of segments 3-5 are not found 
in any known Indian species of Dynomene.
