[21]: Figure 1, located on page 423, has a line drawing depicting the side of the head and a black-and-white 

 photograph showing the living animal. 



[22] : Peculiarly, the collection numbers of the type specimens mentioned in this article and their dates of 

 capture are differ fi-om those given in the preliminary description of the species (ZHAO et al., 1978)! 

 This latter publication is considered the valid, original description of the present species, and the 

 name-bearing type and other specimens in the type series, are those mentioned in this article; 



Holotype: CIB Nr 725049, collected on 1972-10-10 

 Parat>pes: CIB Nr 725048-725057. 



[23]: Namely the second supralabial; see note [5]. 



[24]: Two loreals consecutively arranged, not superposed. 



Trimeresurus tibetanus 



[25]: The literal translation of the Chinese title reads as "A new species of Crotalidae from Xizang". In the 

 English summary, the authors uses the word "Tibetan". 



[26]: The name laotietou is here used as a collective name for the genus Trimeresurus. The Chinese text 

 used this vernacular name rather than the scientific name, hence its regular appearance. 



[27]: A name meaning "Xizang bamboo-leaf green snake" see note [2]. 



[28]: Figure 1 contains five elements, noted (1) to (5) and is divided into two parts, as follows: elements (1) 

 and (2), on page 116: black-and-white photographs showing respectively an overall view of the 

 holotj'pe and a close-up dorsal view of the head; elements (3), (4) and (5) on page 1 17: line drawings 

 of parts of the hoiot>pe showing respectively a lateral view of the head, the general arrangement of 

 dorsal scales at midbody and of color spots, and a ventral view of the tail. 



[29]: The Fudan University is located in Shanghai City. 



[30]: The type locality is given in the English summary as "Naylam, Chokesumo"; we recommend the 

 pinyin transcription of the names given in the Chinese text. The city of Nielamou is also known as 

 Nyalam (see Sun, 1989). 



[31]: Our own counts, according to DowLING's method, give respectively 152 (male) and 159 (female) 

 ventrals. 



[32]: According to Mr WU of the Fudan University, the dorsal head surface of the types was also marked 

 with faint rust-colored marks or lines. 



He gave also us some ecological data. The type specimens were collected in low dense, luxuriant 

 vegetation inside a shallow valley having a subtropical climate in spite of the altitude. 



[33]: The description of the types are partly erroneous. We (PD) examined both types in the Fudan 

 University, and a more complete description is in preparation. The paratype has 1 loreal on the left 

 side and 2 consecutive loreals on the right side; the holot>'pe has 1 loreal at right and 2 consecutive on 

 the left side; figure 1 (3) is erroneous on this point. Moreover, fig. 1 (3) suggests that, in this species, 

 the third supralabial is in contact with the subocular. This is true on the left side of the holotype, 

 whereas they are separated by a small scale on its right side; the third supralabial is in contact with 

 the subocular on the right side of the paratype but separated on the left side. Last, there are 3 

 differentiated supraoculars in the holotype, respectively 3 supraoculars on right side and 2 on left side 

 in the paratype. 



[34]: Namely the lower preocular. 



[35]: The author used Chinese names of these species, respectively Xizang zhuyeqing, Motuo zhuyeqing 

 and Dalin zhuyeqing, the latter one meaning "large-scaled bamboo-leaf green snake". For 

 convenience, we used scientific names in the translation.
