minck's specimen would seem t'> be smaller than either; bat I can- 

 not find any oilier disparity, excepting that of sise, sufficiently 

 marked to establish the existence of a second Bpeciea. Probably t Ik* 

 .smaller island example, from which M. Tenimiuek touk his descrip- 

 tion, may hold the same relation to those From the continent of India, 

 which the smaller specimen of Y. Pearwnii from Amhovna does t" 

 those collected by Dr. Pearson at Darjeeling, of which 1 have spoken 

 in a previous communication. 



In the following Table the dimensions of column Nn. 1 are those 

 of the specimen in the British Museum ; those of No. 2 are from tin- 

 one in my own collection (collected by Capt. Boys) , No, .'! from M. 

 Temminek's description, but reduced to English measure ; ami No. I 

 from Mr. Hodgson's description of Noctulinia lasyura. A specimen 

 bearing the latter name having been forwarded by that gentleman to 

 Dr. Horsfield, has enabled me to identify it with the V, tuilhu of 

 M. Temminek.

Although Mr. Hodgson has forwarded an unquestionable example 

 of this species under the name of Noctulinia lasyura, vet the dimen- 

 sions which are appended to his description are more nearly those of 

 /'. Pearsonii. It is quite possible that the two may have been con- 

 founded. 



During the examination of this singular species, its affinities with 

 the group consisting of J', formosits, V. emarginatus, I . rufb-pictut, 

 and V. Pearsonii become sufficiently manifest. The general form 

 of the head and face, of the tragus, of the organs of Sight and the 

 members of support, the quality and distribution of the for, hut, 

 more than all, the general conformation of t he cranium ami the shoi t- 

 ik>> of the teeth, are points of essential resemblance,-- -whilst the 

 differences are, with the exception of that in the number of the pre- 

 molars, purely external. So external are they, that a neat hand, 



with the assistance of a pair of scissors and a sharp knife, i 

 speedily, with very slight alteration, remove all the external peculiari- 

 ties of Murina. If a very small piece were scooped onl of the outer 

 margin of the ear, it would resemble that of V. Pearwnii . if the
