had all these caught, and examined their mouths, but could find no 

 trace of incisors either above or below. 



Of P. cEliani, the adult female above spoken of. now in the 

 Society's Gardens, has two well-formed incisors above and six below, 

 just as the skull of the specimen obtained by Mr. Blanford in 

 Abyssinia*, which is now in the British Museum. 



In November last Mr. Jamrach had on sale four .Elian's Wart- 

 hogs ; and I sent Mr. C. Bartlett down to examine them, hoping to 

 find a mate for our husbandless female. Mr. Bartlett reported to 

 me that they were unfortunately all of the female sex ; but having 

 at my request taken the opportunity of examining their mouths, he 

 found that all these four animals also had " two incisors in the upper 

 jaw and six in the lower." 



It appears, therefore, that in every specimen examined (eight of 

 P. eethiopicus and five of P. eeliani), the differences of dentition 

 usually held to separate these two species correspond with the ex- 

 ternal characters, and that P. eethiopicus (usually so called) has no 

 incisors above and two small deciduous incisors below, whereas P. 

 eeliani has two permanent incisors above and six below. 



As regards the distribution of these two species, Wagner appears 

 to be quite correct when he comes to the conclusion that P. eethio- 

 picus is confined to the extreme south of Africa f. Our two pairs 

 were both received from Natal. But P. eeliani seems to be spread 

 all over the continent, being met with in Abyssinia and East 

 Africa generally (Rilppell), Cap Verd (Buffon), Ashantee (Viv. 

 Soc. Zool. Lond.), Guinea coast (Pel), Caffraria (Wahlberg), and 

 Mozambique (Peters). 



I may add that there can be little doubt that P. eeliani ought, 

 according to the strict laws of priority, to be called P. africanus, 

 being the Sus africanus of Gmelin (S. N. p. 220), based upon 

 Buffon's " Sanglier du Cap Verd." 



22. Cervus pseudaxis, Eyd. & Soul. 



Hitherto I have called the Formosan Deer Cervus ta'evanus 

 (emended from taiouanus, Blyth). But as Mr. Swinhoe has now 

 examined the typical specimens of Cervus pseudaxis in the Museum 

 of the Jardin des Plantes, and convinced himself that they belong 

 to the Formosan species % (as I have suggested would probably turn 

 out to be the case, in my article on the Deer living in the Society's 

 Gardens§), I think it right to revert to the earlier name, and have 

 accordingly entered this species in the new edition of the List of 

 Vertebrates as Cervus pseudaxis. 



23. Cervus alfredi, Sclater, P. Z. S. 1870, p. 381, pi. xxviii. 



The fine male Deer to which I have recently given the name of 

 Cervus alfredi is still living in good health in the Society's Gardens.
