MARINE CRUSTACEANS. 261 



67. Carpilodes cariosus Ale, 1898. Alcock, iii. p. 86. 



The colour in most of my specimens is not pink but orange-yellow \ One small male from 

 Miladumadulu, however, exactly agrees with Alcock's description of the colouring, and at the 

 same time differs from the yellow-marked specimens in having less extensive patches of colour 

 on the back, and in that the lobules of its carapace are somewhat more compact and less 

 irregular in shape. It is possible that this is the true C. cariosus, while the other specimens 

 belong either to a distinct species or to a variety. 



Dredged in Miladumadulu, Suvadiva, Mahlos, Fadifolu, Male, and South Nilandu Atolls, 

 in 20 — 40 fathoms. 



Genus Carpilius Desm., 182.5. 



68. Carpilius maculatus (Linn.), 1764. Alcock, III. p. 79. 



This species was seen both at Minikoi and in the Maldives. It may be found wedged 

 into holes on the reef just above low water-mark, exposed to the full force of the surf 



69. Carpilius convexus (Forsk.), 1775. Alcock, iii. p. 80 (Fig. 41 B, 42 A). 



Taken in Fadifolu, Male, Minikoi and North Male Atolls on the reef and in lagoons down 

 to 35 fathoms. 



Subfamily Etisinae. 

 Genus Chlorodopsis A. M.-Edw., 1873. 



70. Chlorodopsis spinipes (Heller), 1861. Alcock, iii. p. 169. 

 Taken on the reef in Male and Minikoi Atolls. 



71. Chlorodopsis woodmasoni Ale, 1898. Alcock, in. p. 171. 



Taken on the reef in Male, Fadifolu and Goifurfehendu Atolls, and dredged in 6 fathoms 

 in Male Atoll. 



72. Chlorodopsis frontalis (Dana), 1852. 



1 Etisodes frontalis, Dana. U.S. Expl. Expd. Crust, i. p. 187, pi. IX. fig. 3 (1852). 



[Not Etisodes frontalis, Bori-adaile, P7'oc. Zool. Soc. 1900, p. 588 (1900) = Leptodius sanguineus 

 H. M.-Edw., 1834, juv.] 



The collection contains specimens of a crab which resembles Dana's species in all but the 

 following points: (1) The forepart of the carapace derives its roughness, not from minute 

 granules, but from minute dimples. (2) The carapace is a little broader than in Dana's figure. 

 (3) The chelipeds are not entii-ely " unaiTned," for the wrist bears two blunt teeth on the inside. 



The front and the upper edges of the legs of the last four pairs are finely toothed. The 

 fore edge of the meropodite of the third maxilliped is but slightly hollowed. The length of 

 the carapace is very little more than f of the breadth. 



I have placed this species in the genus Chlorodopsis because the fronto-orbital breadth is 

 a little mo7-e than half the greatest breadth, and because of the outline of the fore edge of 

 the meropodite of the third maxilliped. The front is not broad enough to justify its being 



1 C. vailliantianus also often tends to orange rather than crimson, when preserved in spirit.
