Part I. IXTRODUCTIOX. 



In the ' Proceedings' of our Society for 183G there is nuich and 

 varied information, some of it true and some of it false, about 

 the specialised cutaneous glands of Ruminant Ungulates. On 

 pp. 37-38 will be found a table compiled by Owen * showing the 

 presence or absence of preorbital and inguinal glands in some sixty 

 species of Antelopes. Bennett contiibuted a note on })p. 34-36 

 (m the preorl)ital gland of Ant'dnpe cerricapra; and this was supple- 

 mented by I'emarks from Ogilby on the same gland in this species 

 and in an unidentified species of Gazelle. Bennett also communi- 

 cated (p. 39) a letter from Hodgson on the inguinal glands of 

 Fantholops and on the preorbital glands of Cerviis aristoteJis and 

 of Capricornis thai'. The subject was further discu.ssed by Ogilby 

 (pp. 131-139) in a paper dealing with the preorbital, inguinal, 

 and pedal glands, and other external features in genera, of the 

 families Camelidse, Girafiidiv, Cervid.ie, Antilocaprida% and Bovidjp. 

 Finally (on pp. 6(3-fi8), Gray described the tarsal and metatarsal 

 tufts of vaiious species of Cervida?. 



Eleven years later llodg.son (J. A. S. Bengal, xvi. jit. ii. pp. (>8o~ 

 711, 1847) published a long paper on the .same .subject, ba.sed 

 mainly, but not .solely, uj)on Indian genera of Cervida^ and 

 Boviche, without apparently being aware of the work already 

 <lone by Owen and Ogilby; and in 1868 Owen reprinted, with 

 .slight mollifications, his origin:)! ji.iper, but without incorporating
