another one described in 1977 were raised to specific rank. All these taxa are currently considered valid, 

 although with some doubt for one of the subspecies (see below). 



Translations of these original descriptions were purposely prepared by the second author (HT) of the 

 present paper for our monograph on the Thmeresurus-complex. We wish to share them with herpetologists 

 not fluent in Chinese language or not having easily access to Chinese literature so a larger audience has 

 access to original descriptions and characteristics of these venomous snakes, which are still poorly known 

 outside China. English translations of the original articles are reproduced here with explanatory' notes. 



Systematics 



The seven taxa included herein were all described in the genus Trimeresunts. Two were subsequently 

 reallocated to other genera, although ZHAO &. Adler (1993) were conservative and retained all these taxa 

 in the genus Trimeresiirus. 



We provide below in chronological order of description the current names of these taxa, then the 

 original name, bibliographic data, and, if relevant, the authorship of the new combination. For more 

 information, see also GOLAY et al. ( 1993) and David & INEICH (in press).
