Stat. 316. Febr. 19, 1900. 7° 19.4 S., 116° 49/.5 E. Bali Sea. 538 m. 
1 ova-bearing female. 
A new species closely related to Heteroc. ensifer A. M.-Edw. Carapace 
and rostrum combined little shorter than abdomen. Rostrum, measured 
in a straight line from the orbital margin to the apex, in adult speci- : 
mens one-fifth to almost one-third shorter than the carapace, in young 
individuals longer than it, more or less recuryed. Postrostral crest more 
or less arched and armed together with the upper margin of the rostrum 
with 15—-19, usually 16, teeth, lower margin with 10—12 teeth; first 
tooth of postrostral crest constantly: placed a little posterior to the 
middle of the carapace. Lateral carinae of carapace precisely as in Heteroc. 
ensifer A. M.-Edw. 
First abdominal tergum with a rather high, prominent and 
sharp carina, that ends abruptly, while its anterior margin is sloping 
and oblique. Second tergum likewise with a high, prominent and 
sharp carina, the posterior extremity of which appears more or less 
acute, the anterior usually abrupt. Third and fourth terga also sharply 
carinate, the carina, in each, produced posteriorly into a sharp spine; 
the two spines are equal, rather large, that of the 3rd tergum 
reaching to the middle. of the 4th, that of the 4th to the posterior 
margin of the 5th, in adult individuals. Abdomen for the rest resembling 
that of Heteroc. ensifer A. M.-Edw. 
Appendages also resembling those of this species, but the dactyli of the 
three posterior legs a little longer. Legs of 3rd pair as long as the 
antennal scale, 4th and 5th gradually a little shorter; dactyli of 3rd 
pair in adult specimens a little more than one-third of the propodi. 
Length of adult male and female 140 mm. 
Heterocarpoides nov. subg. 
A new subgenus of the genus Heterocarpus A. M.-Edw., proposed for 
Dorodotes levicarina Sp. Bate. This species indeed has all the characters 
of the genus Heterocarpus, excepting the legs of the 2nd pair, that are 
equal and the carpus of which is composed of 6 joints, of which the 
Ist is nearly as long as the following taken together, the 2nd—5th equal 
and very short; it differs moreover from all the known species of Hetero- 
carpus by a different carination, the post-antennular carina running un- 
interruptedly from near the posterior margin of the carapace into the 
orbital spine, by the post-antennal carina wanting entirely and by the : 
posterior half of the postocular being developed.
