104 INSECTIVOEA. 



more frequently seen in Calcutta than tlie previous one, and, as already stated, it 

 seems to me to be identical with N. cinereus, A. M. Edwards. 



Vosmaer' has described what he has denominated the Bengacdisclie Lidjnard, 

 and which he characterises thus: "Le polls est assez long, fin et Icdneux, mais rude 

 au toucher. Sa couleur est, en generate, le gris ou cendrS jaundtre clair, un peu plus 

 roux S'ur les flancs et aux jambes. Autour des yeux et des or elites, la couleur est 

 aussl unpeu plus foncee, et depuis la tete tout le long du dos regne ral brune." ^ A 

 description in every way appHcable to the example from Bham6 and to the Assam 

 specimens of this race which have come under my observation, and therefore also 

 embracing the Cochin-China form N. cinereus, A. M. Edwards. 



Geoffroy's^ description of N. bengalensis is founded on " le paresseux penta- 

 dactyle du, Bengale" of Vosmaer, of which he gives Bengal as the natural abode, 

 and mentions that the animal has four upper incisors, whereas Vosmaer had stated 

 it had only two premaxillary teeth. Audebert,* however, in his work on Morikeys 

 and Lemm's, remarks that Vosmaer had overlooked the two small outer incisors, the 

 existence of which Geoff. St.-Hilaire had determined by a personal inspection of 

 Vosmaer's specimen which is now in the Paris Museum, where it is ranked in the 

 Catalogue under N. javanlcus, and Bennett* also repeats this statement. Vosmaer's 

 figure, if a correct representation of his specimen, certainly conforms more to the 

 Assam than to the Javan form, the latter being markedly distinguished by the 

 presence of two ocular and two aural brovra bands, and generally by there being 

 only two upper incisors, whereas the head of Vosmaer's figure is a very good repre- 

 sentation of the Assam Nycticebus with four upjaer incisors. 



I am therefore disposed to consider that the Assam, Bham6, and Siam Nyctlcebi, 

 which appear to be one species, belong to the form described by Vosmaer, but the 

 correctness of this suggestion can only be ascertained by the actual comparison of 

 specimens from the foregoing locaHties with the type. 



The figure which M. Audebert® has given of N. tardlgradus is a life-sized 

 representation of Blyth's variety B. It is uniformly rusty-brown with no bands 

 from the eyes, which have the brovm area around them but very little darker than 

 the body colour. The ears are dark, and no brown bands proceed from them to the 

 vertex, and the white which in other species exists between the eyes surrounding 

 their brovra. margin is here replaced by a rufous tint. This is the Burmo- 

 Malayan form, and is smaller than the Assam Nycticebus. Audebert states that the 

 specimen was in the Paris Museum under the Malayan name " Poucan," which is 

 apparently the same as the " Kukimg," figm-ed and described by Baffles'' under the 

 names N. tardlgradus and N. bengalensis, an animal vidthout head-bands, of the
