170 it. Lydehker — Siiralik Antelopes. 



genera of existini^ Antelopes renclers it in many instances a matter 

 of extreme difficulty to be quite sure as to the affinities of their 

 fossil relations. 



1. OrEAS (?) LATIDENS, fiohis. 

 Vide Pal. Ind. ser. 10, vol. iii. pi. xiii. figs. 12, 13. 

 Founded on the upper dentition, which closely resembles that of 

 the Eland. 



2. Strepsiceros (?) Falooneri, n. sp. iwhis. 

 Founded on an immature cranium in the British Museum (No. 

 37262) from Perim Island (Gulf of Cambay), This specimen 

 shows the bases of the horn-cores, and agrees so closely in general 

 characters with the cranium of the existing species of Strepsiceros 

 that it evidently indicates a closely allied, and very probably 

 generically identical, form. 



3. Pal^oryx (? sp. 

 Vid^e Pal. Ind. o/;. cit. figs. 9, 10. 

 Indicated by molars resembling those of the Pikermi forms of 

 this genus. 



4. BOSELAPHUS, sp. 

 Vide Pal. Ind. op. cit. figs. 1,2. 

 Described upon the evidence of the upper dentition. 



5. HippoTRAGUs SiVALENsrs, nohis. 



Vide Pal. Ind. op. cit. vol. i. pi. xxv. fig. 1, 2 [Ajitilope). 

 Originally founded on a female cranium with the crowns of the 

 molars hammered off, and considered to be allied to Antilope cervi- 

 capra ; from which it is, however, widely different. An immature 

 cranium of a male in the British Museum (No. 39558) indicates that 

 this form is closely allied to the existing African Hippotragus niger, 

 and may, at least provisionally, be referred to that genus. 



6. GrAZELLA PORRECTICORNIS, noMs. 



Vide Pal. Ind. ser. 10, vol. i. pi. xxv. fig. 4 {Antilope). 

 Founded on a frontlet and horn-core. 



7. Alcelaphus pal-^tndicus (Falconer). 

 Vide 'Falconer's Palaeontological Memoirs,' vol. 1. pi. xiii. {Antilope). 

 The cranium (B. M. No. 39594) strongly resembles that of 

 Alcelaphus tora, but the direction of the horn-cores is more like 

 that obtaining in A. albifrons and A. pygargus. 



8. Alcelaphus Bakeri, n. sp. nohis. 

 This species is founded on an immature cranium in the British 

 Museum (No. 39698), with a shorter face and more approximate 

 horn-cores than the last species, and presenting a very strong 

 resemblance to that of Alcelaphus pygargus. 



Generically undetermined forms. 

 9. Species a (resembling (Johns) . 

 Two fragments of frontals and horn-cores (B. M. Nos. 18785, 

 1878. jr(j from Perim Island, indicate a very large Antelope with 

 depressed Irontals, resembling Cobus.
