tubercular, of the young animal. The teeth of the adult are also 

 much stronger and larger, the anterior ones becoming less, and the 

 posterior more, lobed and tubercular. In the first set, the false mo- 

 lars are thin and compressed, and the second is distinctly three- 

 lobed; this last is replaced by a strong thick conical tooth with a 

 slight raised margin behind, and the third or new false molar is nearly 

 similar, but furnished with a very small tubercle in the middle of the 

 inner side of the base of its crown. The cheek-tooth of the first set 

 is also compressed and has a small lobe in the middle of the inner 

 side; while in the second set this tooth is triangular, broad in front 

 and narrow behind, with a large distinct lobe on the front of its in- 

 ner margin. It is much larger than the tubercular tooth of the first 

 set which it replaces, and which is little different in form from the 

 first tubercular of the second set, although the latter is also larger 

 and has more prominent and distinct tubercles. 



Mr. Gray observed that it was on this discrepancy between the 

 milk and second teeth that the generic character ofPaguma, before 

 described by him (see Phil. Mag. and Annals, N.S., vol. x. p. 234), 

 was founded, he not having at that period noticed the change that 

 takes place on the shedding of the former set. The description 

 there given was taken from a skull belonging to a young animal 

 about to part with its milk-teeth, which still however remained per- 

 fect, while the jaw had elongated suflSciently to allow of the partial 

 development of the two tubercular teeth of the new set, which were 

 rendered visible by scraping. In this state the true number of 

 teeth belonging to the family was present, the tubercular tooth of 

 the first set still retaining the place of the cheek-tooth of the second, 

 for which it was described. Subsequently, however, Mr. Gray has 

 been enabled, by cutting away the bone below this tooth, to lay bare 

 the true cheek-tooth, which resembles that of the other species of 

 Paradoxurus, to which genus the animal in question must therefore 

 revert. The explanation of this change is the more interesting in- 

 asmuch as the Civets in general appear to attain nearly their full 

 size previous to its occurrence, and consequently do not offer the 

 usual indications of immature age. 



Mr. Gray then proceeded to enumerate the following species of 

 the genus Paradoxurus, all of them, as far as their habitat has been 

 ascertained, natives of India and the Indian Islands. 



Paradoxurus Typus, Pennantii (new sp.), Bondar, prehensilis, 

 Musanga, dubius (new sp.), hermaphrodiius, Pallasii (new sp.), 

 Crossii (new sp.), leucopus, Hamittond (new sp.), larvatus, ( Paguma 

 larvata, Gray, Proceed. Coram. Zool, Soc. i. p. 96 ; Phil. Mag. 

 and Annals, N,S. vol. x. p. 235.) trivirgatus (new sp.), and 

 bi7iotatus. 



To this enumeration Mr. Gray added the indication of an animal 

 known only by a rough sketch brought by Mr. Finlayson from Siam, 

 and deposited in the Library of the East India Company. This he 

 proposed to call Paradoxurus Finlaysonii, and described as being pale 

 brown ; witii a band across the middle of the muzzle, and another 

 across the orbits (including the eyes and expanding on the back of
