Trichys that has come to England, although there have been examples 
of it for many years in the Leyden Museum. The first one, a tailless 
individual, was described by Dr. Giinther as “ Jrichys lipura,” 
under the circumstances detailed in his paper of the present year 
(supra, p. 75). Since, however, I differ from him as to the 
admissibility of the name ‘ lipura’ for a species which normally has 
a long tail, I propose now to rename the species accordingly. 
No better name can be found for it than of its original describer, 
whose judgment in forming a new genus for it is fully confirmed by 
an independent examination of its cranial characters, even after the 
downfall of the peculiarity supposed, and not unnaturally, to belong 
to it of not possessing any trace of a tail. 
As to the alleged applicability of Shaw’s name “‘ Hystrix fascicu- 
lata”? to this Porcupine, I can only express my entire agreement 
with Dr. Giinther’s opinion (J. ¢.) that that name should stand as 
a synonym of Atherura macrura, L. 
The Kina Balu specimen, although only half-grown, shows all the 
characteristics of the genus, and is distinguishable at the first glance 
from Atherura by its short spines and narrow parallel-sided caudal 
bristles. 
3. Second Account of the Fishes obtained by Surgeon- 
Major A. 8. G. Jayakar at Muscat, East Coast of 
Arabia’. By G. A. BouLEnceErR. 
[Received April 11, 1889.] 
(Plates XXV.—XXVIII.) 
At the close of last year the Natural History Museum received a 
second collection of Fishes from its generous correspondent at Muscat, 
Surgeon-Major A. 8. G. Jayakar; this was shortly followed by a 
third, received a few days ago. Other examples of a number of the 
rare or new species enumerated in my preceding list having been 
sent again, I have, in some cases, been able to supplement my former 
descriptions; but all the species enumerated hereafter, and to which 
numbers are attached, are new to the fauna of Muscat. Eight 
of the known species are altogether new to the Indian Ocean, viz. :— 
Erythrichthys schlegeli, Pomatomus telescopium, Chetodon modes- 
tus, Echeneis clypeata, Trigla capensis, Chilomycterus echinatus, 
LEchinorhinus spinosus, and Rhinobatus schlegeli. Five species are 
considered to be new. The Sharks and Rays, which were hardly re- 
presented at all in the first collection, have now reached us in numbers, 
and, from the size and beauty of most of the skins, will, to say 
nothing of the great zoo-geographical interest that attaches to many 
of them, form a welcome addition to the Fish-Gallery of the Mu- 
seum, where Mr. Jayakar’s previous donations of large Sea-Perches, 
Scombroids, Sphyreenas, and Sword-fishes already have a conspicuous
