ii. Front cut into 3 teetli, tlie middle one of which is hardly 

 seen in a dorsal view : antero-lateral horders of carapace 

 with a single tooth, at their anterior end : legs hardly 

 nodular ... ... ... ... ... C. Hilgendorfii. 



2. A dorsal spine on the hepatic region of the carapace, just behind 



the outer orbital angle ... ., ... ... C. de Manii. 



II. Carapace (and appendages also) profusely granular : the regions of the 

 carapace well defined and areolated : — 



1. Carapace subcircular in outline, its antero-lateral borders non- 



dentate, the median frontal tooth the most prominent ... G. ebaltoides. 



2. Carapace pentagonal in outline, its antero-lateral borders dentate, 



the lateral frontal teeth the most prominent ... ... C. Gilesii. 



Cryptodromia pihifera, Alcock. Plate II., fig. 7. 



Cryptodromia tuberculaia var. jnlcifem, Alcock, J. A. S. B., LXVIII., pt. 2, 1899, p. 141. 



Body covered with a short scanty scurfy tomentura which does not conceal 

 the texture beneath. 



Carapace broader than long, convex, smooth, without distinction of regions : 

 the cervical groove broad, shallow. 



Front cut into 3 broad triangular teeth of about equal size, the middle one 

 of which is on a lower plane than the others and is deflexed. 



A sharp tooth near the middle of the upper border of the orbit marks the 

 true inner supra-orbital angle. Outer orbital angle dentiform. Suborbital lobe 

 dentiform and very prominent. 



True antero-lateral border cut into 3 or 4 blunt teeth : in the gap between 

 the 1st tooth and the outer orbital angle two subhepatic teeth — one of which is 

 large — may show up and may, from a dorsal view, look as if they belonged to 

 the antero-lateral border : there are two similar teeth, one alone of which is 

 conspicuous, at the outer angle of the buccal cavern. On the postcro-lateral 

 ))order, at the branchial or cervical groove, is a denticle. 



Wrist and palm, and corresponding joints of first two j^fiir of legs, sharply 

 and profusely nodular or tubercular on the outer surface : fingers compressed, 

 meeting only at tip. 



The third pair of legs, though much slenderer and less nodular than the first 

 two pair and only about half their length, are fashioned on much the same plan, 

 except that the propodite is much shortened : the spinule at the end of the 

 propoditc of this pair is not always big enough to form a chela with the claw-like 

 dactylus. 



Last (4th) pair of legs slender and smooth, a good deal longer than the 

 l>enultimate pair: their propodite has spines at the end of both borders, the
