Nepal and //. javanica of Java. I believe, however, that this is quite 

 a mistake. The two latter species are certainly very closely allied ; 

 but I have no reason to doubt Mr. Waterhouse's determination that 

 they are different. But H. longicauda is apparently quite distinct 

 from either of them, having a slightly elevated crest and being black 

 and white instead of brown and yellow. The Sumatran black and 

 white specimen in the Leyden Museum spoken of by Mr. Water- 

 house (I. c. p. 46) is probably H. longicauda.

Shed spine of Hystrix longicauda (one-half the natural size). 



I exhibit some shed spines of our Hystrix longicauda, which, it 

 will be observed, are at once distinguishable from those of the H. 

 cristata group by being white, with only one nearly central black 

 ring. It will be noticed that in Marsden's figure of H. longicauda 

 some few of the spines are doubly barred with black ; but this is, no 

 doubt, attributable to artistic error. 



I hope to be able to give further particulars concerning Hystrix 

 longicauda whenever either of our specimens dies*. 



* Since this was written, Mr. W. Marshall has kindly supplied me with the 

 following note on the Porcupines of this form in the Leyden Museum :— 



"In the Leyden Museum are examples of two species or races of Hystrix 

 from the Southern Asiatic archipelago,— that is, H. javanica, and a Hystrix- 

 form from Sumatra, under the Museum name H. miilleri, which is unquestion- 

 ably the same as that which you call H longicauda. S. Miiller (Verh. Nat 

 Gesehied. p. 36) has already spoken of the differences between these two races^ 

 of which one comes from Java, the other from Sumatra. In our Gallery 

 here we have of H. javanica three stuffed examples, two skeletons, and three 

 skulls; of H. longicauda (under the MS. name H. miilleri, Temm.) we have one 

 full-grown example from Sumatra, and a very young one in its first year from 

 Borneo. A half-grown individual, which is marked H. javanica, without any 

 locality, is certainly referable to H. longicauda. What v. d. Hoeven intended 

 by H. ecaudata is not clear to me ; and his H. torquata is simply a synonym 

 of H. javanica. The following table gives a comparison of the principal differ- 

 ences between the two allied species : —
