Mr. A. de C. Sowerby has recently sent the Museum a fine specimen 

 from I^atun, Fukien (U.S.N.M., Cat. No. 73140, Collector No. 1294), 

 which is typical of this form in every respect. The internasals are 

 small and separated by 4 scales. Body scale rows 21. 



Through the courtesy of Dr- Thomas Barbour I have examined a 

 Chekiang specimen collected by J. Wright in the Museum of 

 Comparative Zoology (Collector's No. 1177) which clearly belongs to 

 this subspecies and closely agrees with the two other Chekiang speci- 

 mens in the United States National Museum already reported upon 

 by me.^ They all have several scales separating the internasals, dis- 

 tinct nasal and first labial, and intercalated scales between nasal and 

 anterior pit scale, but the specimen collected by Mr. J. Wright (No. 

 1177) at Tunglu, Chekiang, has 23 scale rows as against the normal 21 

 in the others. 



There are also in the collection belonging to the Zoological Museum 

 of the University of Michigan and submitted to me by Dr. A. G. 

 Ruthven for examination, two young specimens of this form. Un- 

 fortunately they are without precise locality but the probability is 

 that they are from some place in Kiangsu. They agree with the 

 above. 



TRIMERESURUS GRAMINEUS YUNNANENSIS (Schmidt) 



1925. Tnmeresurus yunnanensis Schmidt, Amer. Mus. Novit., No. 157, Feb. 13, 

 1925, p. 4 (type locality Tengyueh, Yunnan, China ; type, Amer. Mus. 

 N. Y., No. 21058; Andrews and Heller, collectors). 



Through the courtesy of Dr. Thomas Barbour I have been enabled 

 to examine two specimens from Central Yunnan, namely, Mus. 

 Comp. Zool. No. 14671, from Yunnan-f u, and No. 16734 from Fuchien- 

 hsien. Both have the internasals separated by scales, nasal distinct 

 from first supralabial, and small scales in suture between nasal and 

 anterior pit shield. The gular scales are of a somewhat intermediate 

 character, but there can be no doubt that this form belongs to the 

 highland type. The number of their scale rows is 19.
