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 " Trichys lipura," 

 under the circumstances detailed in his paper of the present year 

 (supra, p. 7^)- 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 {1. e.) that that name should stand as 

 a synonym o^ 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. S. G. Jayakar at Muscat, East Coast of 

 Arabia \ By G. A. Botjlenger. 



[Eeceived 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. S. 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 sjiecies are altogether new to the Indian Ocean, viz. : — 

 Erythrichthys schlegeli, Pomatomus telescopium, Chcetodon wodes- 

 tus, Echeneis clypeata, Trigla capensis, Chilomycterus echinatus, 

 fJchinorhinus 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 preA^ious donations of large Sea-Perches, 

 Scombroids, Sphyraenas, and Sword-fishes already have a conspicuous
