68 QELASINfUS DUSSUMIERF, 



This species bas almost the same distribution as Gel. 

 vocans , our Museum contaiuiug specimens from Nossi-Faly, 

 Java , Makassar and Padang. It is recorded by Milne 

 Edwards from the coast of Mala])ar. It differs from Gel. 

 vocans by the shape of the larger hand ; the inner margin 

 of the immobile finger curves upwards , and is but 

 feebly toothed , the inner margin of the upper finger al- 

 most straight , not arcuate and armed Avith numerous 

 equal very small teeth; the granular crest on the inter- 

 nal surface of the hand near the articulation of the wrist 

 is mucli feebler., and the crest that is found near the ar- 

 ticulatiou of the upper finger in Gel. vocans , does not 

 occur in the other species ; for the rest , the inner surface of 

 the hand is a little granulated. In one specimen the larger 

 hand is very small: the breadth of the carapace of this 

 specimen (the distance between the external orbital angles) 

 is 23 mm. and the length of the larger hand but 22 mm. 

 In a typical specimen however that has a breadth of 24 

 ram. , the length of the larger hand is 45 mm. 



Gelasimus Dussumieri M. Edw. 



Milne Edwards, 1. c. pag. 148. PI. IV, fig. 12. 



Some specimens ot a Gelasimus have been collected by 

 Messrs. Pollen and van Dam at Nossi-Faly and described 

 by Mr. Hoffmann under the name of Gelas. Dussumieri 

 Edw. (Hoffmann, Crust, de Madagascar, pag. 17). These 

 specimens indeed agree entirely with specimens from Zan- 

 zibar , described by Hilgendorf under that name (Hilgen- 

 dorf, 1. c. pag. 84, Taf. IV, fig. 1), but I am not 

 convinced that these specimens belong to Gel. Dussumieri, 

 because the shape of the front seems to me to be some- 

 what different: only a comparison with typical specimens 

 of Gel^ Dussumieri may decide in this question. The Mu- 

 seum contains another single male specimen from the Mo- 

 luccas, collected by Macklot; this specimen agrees in many 

 respects with the Nossi-Faly specimens , but the front is more
