form the side wall of nasal opening, is very much more prominent 

 and raised up than in the Andaman species. 



As was pointed out by Owen, the scapula of the two forms also 

 presents several points of distinction, the coracoid process is much 

 more developed in the Australian species than in the Andaman 

 form, the notch between the coracoid process and the anterior 

 part of the blade is also strongly developed in the Australian, where- 

 as in the Indian species there is hardly any notch at all; the curve 

 of the posterior edge of the blade is very much greater in the 

 Andaman than in the Australian example ; the acromion too is much 

 higher and bigger in the Andamanese form. 



Curiously enough the skull entered in Blyth's Catalogue under 

 the number 462B, and believed by him to be the skull of an 

 Australian specimen, agrees in every way with the Andamanese 

 species in the Museum, and has therefore been entered here 

 under the name of H. dugong ; it is very possible that there has 

 been some mistake in the locality of the skull in question. 



It seems to be generally acknowledged that the Red Sea form, 

 (H. tabernaculi of Riippell) is indistinguishable from the Indian 

 species.

Order EDENTATA 



The Order Edentata is a very polymorphic one and not easily 

 defined ; the forms included in it have, however, the following 

 points of structure in common ; teeth present or absent, when 

 present, consisting of molars only, and springing from persistent 

 pulps devoid of enamel.
