Gonodactylus cultrifer. 



Gonodactylus cultrifer, White, Proc. Zool. Soc. p. 96, (Annulosa) 

 pi. xvi. fig. 1 (1850). 



Carapace smooth, with the antero-lateral and postero- 

 lateral angles rounded and the posterior margin straight. The 

 rostrum is quadrilateral, smooth, with the sides slightly con- 

 vergent distally, and the anterior margin straight. The first 

 thoracic segment is not produced on the sides ; second and 

 third with the lateral processes rounded. First to fifth post- 

 abdominal segments smooth ; there is a small spinule at the 

 postero-lateral angles of the fifth segment ; sixth segment 

 armed with six longitudinal carina?, which terminate in 

 spines, another carina on each side is represented only by 

 tubercles near the anterior margin of the segment ; terminal 

 segment with an elevated laminiform median crest, which in 

 vertical height nearly equals the space between its base and 

 the lateral margin ; the upper margin of this crest is arcuate 

 and terminates in a small spine ; on either side of the median 

 crest are two longitudinal carina? ; the spines of the lateral 

 margins are not flattened and dilated. The basal portion of 

 the dactyli of the raptorial limbs is not much thickened ; the 

 terminal portion is elongated and knife-shaped, and its inner 

 margin is armed with two teeth. The outer spine of the 

 basal prolongation of the uropoda is much longer than the 

 inner ; and the outer margin of the penultimate joint of the 

 outer ramus is armed with nine flattened spines (not twelve as 

 in G. scyllarus). Length nearly 4 inches. 



Hab. China. 



Two males are in the British-Museum collection. The 

 integument is remarkably thin and membranous, and, in the 

 dried state, is of a reddish-pink colour, paler in the middle 

 line and in other places.
