522 ME. R. I. POCOCK ON THE 



Anotlier specimen, subsequently obtained, was found in the 

 forest at an altitude of 1000 feet under rotten leaves. 



There are, I think, no reasonable grounds for doubting that 

 these specimens are referable to the species ixa,\ned julifonnis by 

 Gruilding — a species based upon an example from the same 

 locality, which was said to have 33 pairs of legs. So, too, does 

 it seem that they are almost certainly co-specific with the spe- 

 cimens from Caraccas described as Edwardsii by Sedgwick. Por 

 the two sets of specimens agree in colouring, number of legs, 

 armature of jaws, and apparently in the shape of the papillae. As 

 for Edwm^dsii of Blanchard, I suspect that it has been redescribed 

 as Imtliurni by Sclater; for it is more probable that a specimen 

 from French Guiana should be co-specific with others from 

 British Guiana rather than with a third set from Caraccas. More- 

 over, bearing in mind the fact that males seem to be scarcer than 

 females, it seems more likely that the type of Edwardsii was of 

 the latter sex than of the former. If this prove to be the case, 

 this type will agree with the female of Imtlmrni, and differ from 

 that oi juUformis in the number of its legs.

Colour of dorsal surface chocolate-brown, of ventral surface 

 light brown. 



PapillcB with basal part conical, as in the specimens from 

 Pemerara named Imthurni. The inner blade of the jaws fur- 

 nished with a larger number (10-11) of minor teeth. 



Number of pairs of legs 28-31. 



Locality. Trinidad; Dominica (G^. A. Ramage). 



Mr. Eamage obtained at Laudat in Domiuica three female 

 examples of a Peripatios., each having 30 pairs of legs, which 

 seem to be specifically identical with Kennel's specimens from 

 Trinidad. Kennel identified his examples as Edicardsii of 

 Blanchard, and very possibly quite correctly. Prof. Sedgwick, 

 however, acting upon the supposition that his specimens from 

 Caraccas were Edwardsii of Blanchard, and recognizing their 

 distioctness from Kennel's examples, proposed the name trini- 

 dadensis for the latter. This name can provisionally stand 

 until the veritable Edivardsii is rediscovered.
