XXXIII. Genus Goxodactylus Latr. 



57. GONODACTYLUS CHIRAGRA Fabr. 



Squilla cJiiragnt, Fabr. Ent. Syst. p. 513 (1793). 



Gonodactyhts chiragra, Latr. Encycl. Moth. x. p. 473 (1825) ; 

 Miers, Ann. Mag. Nat. Hist. (5) v. p. 118 (1880); Borradaile, 

 P. Z. S. 1898, p. 34. 



Loc. Pulau Bidan, Penang ; Kota Bliaru, Kelantan. 



A male and two females from Palau Bidan ; four males and 

 seven females from Kelantan. A single male of the var. smithii 

 Pocock from Kelantan. 



Although the general colour of the latter has been much darkened 

 by the formol in which these specimens were preserved, it is still 

 quite possible to discern the five dark spots on the sides of the 

 abdomen that Borradaile has noted in his examples of var. smithii. 



Length : c? 2j in., $ 4| in., $ 2 J in., the smaller examples 

 ranging from I to 1 in. 



58. GoxoDAcrrLCJS cultrifer White. 



Gonodacti/his cultrifer, AVhite, P. Z. S. 1850, p. 96 (Annulosa), 

 pi. xvi. fig.'l ; Miers,' Ann. Mag. Nat. Hist. (5) v. p. 117 (1880). 



Loc. Kota Bharu, Kelantan. 



A male without the raptorial limbs. Length 4| in. 



I may note that the rostrum does not nearly reach the base of 

 the eye-peduncles as it appears to do in White's figure. Further, 

 the number of spines on the outer edge of the penultimate joiut 

 of the exopodite of the uropods is eight ; White's figure represents 

 eight only, but both he and Mr. Miers give the number as nine in 

 the text. 



The submedian spines of the telson consist of a short, fixed, basal 

 portion bearing a slightly longer movable spine. 



XXXIV. Genus Gebiopsis A. M.-Edw. 



59. Gebiopsis intermedia de Man. 



Gebiopsis intermedia, de Man, Mergui Crust, p. 256 (1888). 



Loc. Pulau Bidan, Penang. 



Numerous examples; ranging from 42mm. in length down- 

 wards. The long hairs on the lower margins of the meropodites 

 of the first two pairs of legs would appear to act as a sifting 

 (? sensory and selecting) apparatus for food ; for if these legs be 

 thrust somewhat forwards and at the same time Hexed upwards at 

 the mero-carpal joint, these hairs will be found to form a complete 

 guard to the buccal cavity. 



XXX Y. (iriius Callianassa. 



60. Callianassa sutim, ip. n. (Plate XXXIV. fig. 2.) 

 Loc. Biota Bharu. Kelantan. ■
