MR. R. H. BURNE ON THE ANATOMY OP THE [May 25, 



race is Himalayan, it appears to me that it will be best to follow 

 Dr. Blanford's usage and retain the name U. torquatus. As I 

 have on a previous occasion shown that the Bruang ( U. malayanus) 

 ranges into Sze-chuen *, we have now evidence of the occurrence in 

 that province of two species of Black Bears. 



Before concluding, I may refer to the type skull of U. formosanus 

 of Swinhoe f, which is contained in the British Museum Col- 

 lection (No. 70.2.10.9). That this skull indicates a bear specifically 

 identical with U. torquatiis appeal's to me indisputable — in the 

 sense in which I regard species. At the same time, it is so much 

 wider and shorter than the skull of U. torquatus typicus that it 

 must, without hesitation, be regarded as representing a distinct 

 race, with the designation U. t. formosanus. This will be apparent 

 from the following measurements : — 



typicus. formosanus. 



Basal length of skull 10*15 ins. 9'1 ins. 



Maximum zygomatic width of do. ... 6*5 6"95 



Length of last 3 upper cheek-teeth ... 2-6 2*25 



The Formosan skull (text-fig. 186, 0) is distinguished, moreover, 

 by the absence of any distinct bevelling away of the oviter side of the 

 talon of the last cheek-tooth, which in consequence has nearly parallel 

 sides. The last lower molar (text-fig. 187, 0) is broad and short, 

 so that it appears more rounded than the corresponding tooth of 

 tyjncus, and thus very different from that of macJteillL In its 

 shortened and wider form the skull of U. t. formosamts makes a 

 slight approximation to that of U. inalayanus, which, however, is 

 broadly distinguished by its still greater expansion, the excessive 

 size of the palate, and the smaller cheek-teeth, more especially the 

 last. 



3. The Anatomy o£ the Olfactory Organ o£ Teleostean Fishes.

[Received May 10, 1909.J 



(Text-figures 188-213.) 



The coarse anatomy of the olfactory organ in the Teleostean 

 Fishes seems to have received too little attention. Reference to 

 the leading old and modern text-books (Milne-Edwards, Owen, 

 Gunther, Cambridge Natural History, Parker and Haswell, 

 Wiedersheim, Gegenbaur, &c.) leaves the general impression that 

 apart from a few isolated cases, the organ is remarkably constant 

 and consists of a pair of simple concavities upon the fore-part 

 of the face opening to the exterior by a pair of nostrils and each 

 containing a grcMp of olfactory laminfe arranged rosette-wise
