56 NILS GYLDENSTOLPE, THE SWED1SH ZOOLOGICAL EXPEDITIONS TO SIAM. 



The type of this species is said to liave come from Siarn though most certainly 

 not southem Siarn as stated in the Catalogue of the Ungulate Mammals in the Brit. 

 Mus. Nat. Hist. vol. IV. 1915 p. 105. In the southern parts of Siarn the Thamins do 

 not occur at least not much further south than the latitude of Bangkok. Outside Sia- 

 mese territory it inhabits Oambodia and Hainan, being replaced in Burma by the true 

 C eldi eldi. 



Cervus porcinus annamiticus. Heude. 



The Hogdeer inhabiting Siarn belongs to the form which was described by Heude 

 under the name of Hyélaphus annamiticus (Mém. Hist. Nat. Emp. Chinois, vol. II. 1888 

 p. 50). This race was founded on specimens from Annam but the range also includes 

 Siarn according to Lydekker (Cat. Ungulate Mammals, vol. IV. 1915 p. 58). 



During my journey I only observed some hogdeers on the grassy plain of Nong 

 Bea in Northwestern Siarn, but as I was out hunting for a tiger the deer were not shot 

 though it eould have been done easily as they were running up quite close to our ele- 

 phants. 



At the neighbourhood of Chieng Hai, hogdeers are also said to occur on the great 

 plains which surround that place, but during my excursions there I never met with it 

 nor did T see any tracks which eould have been stated as belonging to these pretty 

 deers. 



In the Eastern parts of the country they are also said to occur at least in the Chanta- 

 boon Province, where they are stated as being rather common and hunted on horse- 

 back. 



Capricornis sumatrensis milne-edwardsi. David. 



The distribution of the different species and subspecies of the Goat-Antelopes is 

 still very imperfectly known, and much work is still to be done until this question has 

 been properly settled. 



Especially of the Siamese forms we know very little. The latest papers on the sub- 

 ject being that one of Pocock published in the Journal of the Bombay Natural History 

 Society vol. 22. 1913. p. 296—310 and that one of Irwin in the Journal of the Natural His- 

 tory Society of Siarn vol. I. No. 1, 1914 p. 19—26. 



Irwin, who chiefly disgusses the Siamese forms, comes to the conclusion that there are 

 at least two different forms : one being characterized by having ruf ous coloured legs and 

 the other one having no ruf ous at all being merely black and grey or white with dirty 

 white legs. According to Irwin this form is nearest allied to Capricornis svmatrensis 

 ihar Hodgs. previously only known from Nepal, Sikhim and Chumbi. Irwin further 

 says (tom. cit. p. 22.): »I have never heard of the ruf ous variety occuring in Siarn north 

 of Latitude 12° 40' N.; all the specimens I have seen or heard of from the north of that 

 line have only black and white hairs in their pelts ». In this point Irwin, however, seems 

 to be wrong.
