Carcinological Fauna of India. 147 
Jobules or tubercles, of which only 2 belong to the true antero-lateral 
border, the other 3 being on the subhepatic border and at the outer angle 
of the buccal cavern. 
A granular tubercle on the postero-lateral border, just behind the 
“cervical” groove. 
Legs and chelipeds crisply granular, the chelipeds and first 3 pair 
of legs being also nodular: the nodules on the carpal joints being 
prominent and acute. 
Last 2 pair of legs very slender, hardly half the length of the first 
2 pair, ending in hook-like dactyli, not cheliform. 
All the abdominal terga are symmetrically sculptured and granular. 
In the Indian Museum are 12 specimens, from off the Malabar 
coast, 29 fathoms. 
The carapace of an egg-laden female is § millim. long and 83 millim. 
broad. 
This species is easily distinguished from D. ebalioides (1) by the 
sharply pentagonal carapace and less-completely isolated areolew, (2) by 
the much more prominent front, (3) by the antero-lateral borders being 
broken by irrregular tubercle-like lobules, and (4) by the more abund- 
ant sculpture of the abdominal terga: in everything but the form of 
the meropodites of the chelipeds and first pair of legs it strongly resem- 
‘bles Petalomera. 
Subgenus PeTALOMERA, Stimpson. 
Petalomera, Stimpson, Proc. Ac. Nat. Sci. Philad. 1858, p. 226: Ortmann in 
Bronn’s Thier Reich (/oc, cit.) p. 1155 (name only). 
Petalomera closely resembles Cryptodromia, especially those species 
(e.g. Oryptodromia ebalioides and Gilesii) in which the carapace is 
granular and has the cervical and branchial grooves both well deve- 
loped ; and, indeed, only differs from Oryptodromia in having the upper 
border of the meropodites of the chelipeds and first, or first two, pair 
of legs produced to form a crest so high and thin as to give the joint a 
petaloid shape. 
As in Cryptodromia the sternal grooves of the female are widely 
separated, and end on the second segment of the sternum. As in 
Cryptodromia lateralis, there is a small epipodite to the chelipeds. 
There can be little doubt that, as Bouvier (Bull. Soc. Philomath. 
Paris, 1895-96, p. 52) has remarked, Petalomera is a form slightly more 
primitive than Dromia.
