154 MB. OLDFIELD THOMAS ON" [June 4, 



This Oobius, which I have much pleasure in naming after 

 Mr. Percival, is closely allied to another large Arabian species, 

 described by me from specimens obtained at Muscat by Dr. 

 Jayakar, G. jayakari (P. Z. S. 1887, p. 663, pi. liv. fig. 2). It 

 differs from G. jayakari in the shorter mouth, not extending to 

 below the eye, in the broader interocular region, and in the 

 shorter caudal peduncle.

1. Notes on the Type Specimen o? Rhinoceros lasiotis Sclater; 

 with Remarks on the Generic Position of the Living 

 Species of Rhinoceros. By Oldfield Thomas. 



[Eeeeived May 7, 1901.] 



On August 31st, 1900, there died in the Gardens of the Society 

 the famous female Ehiuoceros from Chittagong which has so often 

 been referred to in our 'Proceedings,' and the characters of which 

 it is only fitting should be here noted, now that its skull and head- 

 skin have passed into the possession of the National Museum. 



As the animal was captured in January 1868, its age at death 

 was more than 32 years. 



The first reference to this specimen is an account of its external 

 characters given by the late Dr. Anderson, the Superintendent of 

 the Calcutta Museum (P. Z. S. 1872, p. 129). Then followed 

 {t. c. p. 185) an announcement of its purchase for .£1250. In 

 March of the same year (t. c. p. 493, pi. xxiii.) our Secretary gave 

 the history of the specimen's capture, and a figure of it, and in 

 a footnote assigned to it the name of R. lasiotis, given after 

 comparison with a Malaccan example of R, sumatrensis which 

 arrived in August. In November {t, c. p. 790) he gave his full 

 reasons for separating the two forms, accompanied by figures of 

 the heads, and of the Malaccan specimen. 



Dr. Gray, however (Ann. Mag. N. H. (4) x. p. 207, 1872), with 

 a total disregard to the geography of the question, considered that 

 it was the Chittagong animal that was the true B. sumatrensis, 

 assigning the Malaccan animal first to his B. crossii(P. Z. S. 1854, 

 p. 250) and afterwards (Ann. Mag. N. H. (4) xi. p. 357, 1873)
