iiuus, which has lon^ remained a problem to zoologists, must be referred to 

 iexual relations. In support of this opinion he has referred to the condition! 

 of tills organ in some old Indian Deer formerly in the possession of th©" 

 Zpolog'cal Society in the Gardens in Regents Fark. 



Professor Owen at one time eonceived it possible that the secretion of 

 these glands, when rubbed upon projecting bodies, might servo to direct 

 individuals of the same species to each other. lie endeavoured to test the- 

 probability of this supposition by preparing a tabular view of the relations: 

 between the habiti> habitats of the several species of Antelopes and their- 

 fuborbital, maxilliary, post-auditory, and inguinal gland-:, in order to be able; 

 to compare the presence and degrees of development of these glands with 

 the gregarious and other liabits of the Antelojx^-Tribe- He has stated^ 

 however, that it was evident from this table that there is no relation betweea 

 the gregarious liabiLs of the xlntelopes which frequent the plains and the- . 

 presence of the suborbital and mu?;:illary sinuses; since these, besides being- 

 altogether wanting in some of the gregarious species, are present in many 

 of the solitary frequenters of rocky mountaineous districts. The suppositioa 

 therefore that the seci'etion might serve, when left on shrubs or stones, to. 

 direct a straggler to the general herd, falls to the grcimd. (' Zool. Froc.,*' 

 183G.) 



The osteologies! structure of the Deer-Tribe is such as wcadd be ex-, 

 pected when it was necessary that the bony framework should exh.ibit a. 

 union of lightness and strength necessary for an animal vvhose life is to depend 

 ©n its agility and defensive pov>'er3. 



The CervidiZ are v/idely spread, and seem capable of being so modified 

 fis to withstand tlic extremes of heat and cold. 



'i'he {bllcv,'iug arrangement of the Deer is proposetl by Dr. J. E. Gray : 



A. The Deer of the Snowy Regions have a very broad muzzle, entirely 

 covered with hair. The horns are expanded and palmated ; and the fawna 

 are not spotted. 



a. The Alcine Deer have no basal ar.terior snag to the horns, and a' 

 fmall bold muSe between the nostrils, as the genus Alces. 



b. Tlie Ranger! ne Deer have a large basal anterior snag to the horns 

 tlose on the crowa or burr, and no muffle, as Tarandus. 



Jj. The Deer of the Temperate or Warmer Regions have a tapering- 

 niazzie ending iii a bald muffle. The fawns^ and scmetimes the adults, aro: 

 fpotted. 



c. The Elaphine Deer have a distinct anterior bas-al snag to the horns^ 

 the muule broad, and separated from the .;p by a hairy band ; and the tuft 

 ef hair on the outside of the hind leg, ab-^ve the middle cf the metatarsus, aa 

 Cervus and Dama. 



d. The Ruslne Deer have a distinct anterior basal snag to the horns ; 

 the muSe very high, and not separate from the edge of the lips ; and the 

 tu t of hair on the outside of the hind leg, above the middle of the meta- 

 fersus, as Rucervus, Panolia, Rusa, Axis, Hyeiaphiis, and Ccrvidus. 



e. Tue Capreoline Deer have no basal anterior snag to the horns, thO"
