namely P. sorici'nus, Thor., and P. flavopilosus, Sim,, will 

 fall into this genus, and also MygaJe stridulans of Wood- 

 Mason, the type of which I hope is still in the Museum at 

 Calcutta. The figure of stridulans is not accurate enough to 

 do more than show that the anterior legs are stronger than 

 the posterior, Avhich seems to prove that specimens which 

 Mr. Peal has subsequently sent to England from Assam as 

 stridulans are not in reality that species ; for these speci- 

 mens, for the opportunity to examine which I am indebted 

 to Mr. O. E. Janson, are referable to my genus Lyrognathus, 

 with Yerj strong hind legs. 



Genus LyPvOGNAThus, nov. 

 Lyrognathus crotalus., sp. n. 



This species is based upon a spider from Assam which 

 offers the characters pointed out in the generic diagnosis. I 

 may further add that the carapace is moderately high in 

 front, is much longer than wide, and has a crescentic fovea. 

 The scopuke on the legs are very well developed, especially 

 that on the fourth postarsus, and all are entire, except that on 

 the tarsus of the fourth, which is completely divided. 



The cluster of keys on the maxilla blends both proximally 

 and distally, and externally with the external fringe of hairs, 

 the two together occupying nearly the whole of the area 

 between the suture and the internal or oral fringe : the keys 

 lying next the oral fringe are the longest of all, distinct from 

 the rest, and strongly clavate. There appear to be only 8, 

 or perhaps 9, teeth, which ])osteriorly decrease in size, on the 

 internal side of the lower edge of the mandible. 



Total length 26 millim. ; length of carapace 18*5, width 

 10. 



In some of its characters, e.g. in the approximate equality 

 in length of the protarsus and tibia of the fourth leg, and 

 the much greater length of the patella and tibia of the 

 fourth than of the first, as well as in the large size of the 

 scopula3, this genus approaches Cyriopagopus of Simon from 

 Tavoy. But in the latter the scopula on the fourth protarsus 

 is divided by a line of setae, and occupies only the distal third 

 of the segment.
