GYMNURA GYMNURA MINOR, new subspecies. 



Type.— Skin and skull of tuliilt male, Cat. No. 86783, U.S.N.M., 

 collected at Trong, Lower Siam (on Kliow Nok Ram, 2,000 feet 

 altitude), January 12, 1899, by Dr. W. L. Abbott. 



Diagnostic chm^acters. — Similar in all respects to the typical race, 

 but averaging- distinctly smaller throughout. See fig. 1, Plate 34. 



Color. — The color of fh/mnura gynmiura jnitior does not differ 

 essentially from that of O. g. grgmnura., but there is a tendency to 

 have more white about the head, neck, shoulders, and upper portion 

 of back, as well as a narrower and less conspicuous black super- 

 cilliary stripe. 



Skull and teeth. — These possess the same relative shapes and pro- 

 portions in Gymnura gymnura minor as they do in G. g. gymnura, 

 but average distinctly smaller throughout. See fig. 1, Plate 35. 



Measiirenients. — A series of four adults, all from Trong, give the 

 following extremes of measurements: Head and body, 311-335 mm.; 

 tail, 216-241; hind foot, with claws, 58-59; basal length of skull, 

 67-71; upper tooth row (all teeth, alveoli), 40-42. See table, page 

 455. 



Specimens examined. — Four from the type-locality, 2 from an 

 altitude of 2,000 feet, 1 from 1,000 feet. The altitude for the remain- 

 ing specimen is not known. 



Distrihution. — Trong, Lower Siam, extending northward into 

 Tenasserim. The small size of individuals from the latter country 

 has been mentioned by both Dobson" and Blandford.^ Bonhote '^ 

 remarks that " the Malayan form appears to be smaller than the 

 Sumatran race."
