Genus TYLOTOTRITON " Anderson.

 T. verrucosus).

Thus far only two species of this genus are known, namely, T. verru- 

 cosus, wliich is known from the eastern Himalayas to the mountains 

 of Yumian, and the present species, which has been found only in 

 Okmawa Shinui. Doctor Anderson has given a detailed description, 

 with illustrations, of the anatomy^ of the type species. 



The nearest related genus appears to be Pleurodeles , the only 

 species of which, P. waltl, is confined to the southwestern portion of 

 the Pyrenean peninsula and the northern portion of Morocco. The 

 two genera agree not only in the singularly pointed ribs protruding 

 tlu-ough the sides of the body, sometimes even perforating the skin, 

 but also in the forward extension of the vomero-palatine teeth. 



The present distribution of these forms — one in vSpain, one in the 

 Himalayan region, and one in the Riu Kiu Archipelago — is suggestive 

 of the antiquity of this type of urodeles.

Description. — Adult; Sci. Coll. Tokyo, No. 67; Okinawa (figs. 1-6). 

 Vomero-palatine teeth in two longitudmal series, meetmg in front 

 and commencing some distance anterior to a line through the anterior 

 border of the choaniB, then proceeding backward nearly parallel, but 

 considerable distance apart, then at the beginning of the posterior 

 third sharply diverging; tongue nearly circular, its diameter more 

 than half the width of the mouth, extensively free on the sides, less 

 behind and least in front; nostrils near the tip of the snout, and half- 

 way between the top and the edge of the lip, their distance from each 



oFrom "TvXooTOi, knobbed." "Along the body a lateral line of equidistant, 

 large, rounded, knob-like, porous, glandular tubercles, terminating at the root of the 

 tail. The second to fifth epipleural processes and the extremities of the remaining ribs 

 terminate in the knob-like lateral glands." Anderson, Proc. Zool. Soc. London, 

 1871, p. 423.

c "Named after Dr. J. Anderson, to whom science is indebted for the discovery of 

 the remarkable newt on which he established the genus Tylototriton in 1871." John 

 Anderson was born in Edinburgh, October 4, 1833; superintendent of Indian Museum, 

 Calcutta, from 1865 to 1886; then occupied with the study of the fauna of Egypt till 

 his death on August 15, 1900. He visited Japan in 1884.
