90 A. Alcock — Cardnologieal Fauna of India. [No. 1, 



mate joint or palm slightly rugose externally, and with two longitudinal 

 and parallel grooves on its outer surface ; fingers short, robust, toothed 

 on their inner margins and with the apices not excavated. The 

 ambulatory legs are somewhat compressed and clothed with long fulvous 

 hairs ; their merus-joints are spinulose on their upper margins. The 

 postabdomen of the male is five-jointed, the third to fifth joints being 

 coalescent. Length 8| lines, breadth nearly 1 inch 1 line. 



This species has been hitherto known only from the very short 

 generic definition of Dr. Stimpson, which, however, embraces all the 

 characteristic peculiarities of the species, and which agrees exactly with 

 the example before me, except in one point. Stimpson says (1. c), 

 " Antennae ut in Carpilio" In the specimen now before me the 

 antennae are of the same structure as in Liomera, the basal joint being 

 very short and united at its summit to an inferior prolongation of the 

 front, and not, as in Carpilius, joined to the front along its inner margin. 

 I have little doubt that Stimpson erroneously wrote Carpilius for 

 Liomera, as he does not say that Lachnopodus is distinguished from 

 Liomera by any peculiarity in the structure of the antennae. 



I do not think that Lachnopodus is generically distinct, as Milne 

 Edwards has described a Liomera (L. longimana) with hairy ambulatory 

 legs." (Miers.) 



Genus Lioxantho. 



Carapace broad, moderately or strongly convex in its anterior two- 

 thirds, flat posteriorly ; the gastric region is fairly or faintly delimited, 

 and one or two short furrows may pass on to it obliquely from the 

 intervals between the lobes of the antero-lateral margin, but beyond 

 this there is no distinct division of the carapace into regions or sub- 

 regions. 



The antero-lateral borders are much like that of Liomera, being 

 divided into 4 broad blunt lobes, of which the first two are so much 

 coalescent as to really form but one. 



Front somewhat deflexed, bilobed, or sinuous and notched in the 

 middle line. Fron to-orbital borderless than half the greatest width of 

 he carapace. 



Orbital margin and antennae as in Xantho. 



Anterior edge of merus of external maxillipeds a little more 

 oblique than in Xantho. 



Chelipeds either subequal or unequal in both sexes, fingers pointed. 

 Legs subcylindrical. 



Abdomen of male five-jointed, the 3rd -5th somites coalescent.
