prominence of the hepatic region, and the postero-lateral margin up 

 to the level of the base of the 1st pair of legs, are distinctly beaded. 



3. The thoracic sinus has no definite boundary in front, although 

 it is deep and defined ventrally by large pearly granules as in L. curningi. 



4. The inner edge of the upper surface of the wrist hears a row 

 of granules, which is continued on to the base of the hand. 



5. The fingers are only half the length of the hand. 



An adult egg-laden female from Bombay has the carapace 13 millim. 

 long and 13 millim. broad.

Leucosia elata, A. Mime Edwards, Nouv. Archiv. du Mus. Vol. X. 1874, p. 41, 

 pi. ii. fig. 2. 



Carapace as broad a.s long, hexagonal, with the antero-lateral 

 borders strongly convex" and smooth : the true postero-lateral border 

 is clothed with a strip of dense dark-coloured fur: there are also a few 

 scattered stiff hairs on the posterior part of the epibranchial regions. 



The thoracic sinus is a simple cavity, deep, sharply defined an- 

 teriorly, containing a good many hairs and a line of tiny granules, 

 besides the row of 2 or 3 larger pearly granules (situated above the 

 base of the chelipeds) which define it ventrally. 



The front is prominent, broader than long, concave in the mid- 

 dorsal line and distinctly bilobed. 



The arm is markedly trigonal with the antero-extemal angle expanded, 

 its upper surface is bounded internally by a row of pearly tubercles, 

 externally by a row of pearly granules, and is otherwise smooth, except 

 for a few granules ^lmost hidden in hair and a, single larger tubercle 

 at its base. The wrist is smooth and subglobular, with obscure traces 

 of cirination along its outer surface. The hand is a little longer 

 than broad and has its outer edge strongly carinate, the carina being 

 continued on the mobile finger, where, however, it is less marked: the 

 little lobule at the ba,se of the inner margin of the hand is beaded all 

 round its edo-e. The fingers, which are not much shorter than the hand, 

 meet only at the tip, and have their opposed edges smooth throughout. 



The legs are much compressed, and have the carpopodites strongly 

 carinate dorsally, the propodites strong-ly carinate dorsally and ventrally. 

 and the dactyli extremely slender and hardly as long as their propodites : 

 the meropodites also of the last pair are carinate dorsally. 



Colours in spirit: porcelain white or pale yellow. M. A. Milne 

 Edwards describes the colours as bright greenish grey with numerous 

 specks of orange red.
