DINODON" RUFOZONATUM (Cantor). 



(Herpet. Japan, L907, p. 3 



Common in Formosa, though not recorded as being in any of the 

 collections recently made there. 



DINODON SEPTENTRIONALE RUHSTRATI (Fischer.) 



(Herpet. Japan, L907, p. 370). 

 Nothing has been added since. 



CALAMARIA BEREZOWSKII Guenther.

Boulenger suggests'' that Guenther's Calamaria herezowskii "is 

 probably not specifically separable" from C. pavimentata. This may 

 be so, but for the reasons given in my Herpetology of Japan, p. 375, 

 I "can not consider the question finally settled," and therefore prefer 

 to leave the nomenclature undisturbed until sufficient material shall 

 have accumulated to make a final disposition of these forms possible. 



BOIGA KRiEPELINI Stejneger. 

 (Herpet. Japan, 1907, p. 381). 



1901'. Boiga brsepelini Stejneger, Proc. Biol. Soc. Washington, vol. 15, p. 1G. — 

 Dipsadomorphus hrxpelini Boulenger, Ann. Mag. Nat. Hist. (8), vol. 

 4, Dec. 1909, p. 495 (Kankau and Kosempo, Formosa) 



The additional specimens listed by Boulenger make it appear 

 probable that this snake is not so rare as its late discovery might 

 suggest. 



PSAMMODYNASTES PULVERULENTUS (Boie). 



(Herpet. Japan, 1907, p. 383). 

 Nothing added to the status of this snake in Formosa. 



"No further light has been shed on the alleged occurrence of Lycodon aulicus 

 (Linnaeus) in Formosa | Herpet. Japan, t907, p. 358). 



In this latter work (p. 356, footnote) I staled that inasmuch as Boie himself, in 

 1827, fixed L. audax as the type of Lycodon, which was established in L826 without 

 designated type, this generic name must be retained for the South American Lycog- 

 nathus. It appears, however, that Fitzinger (Neue Class. Kept., L826, pp. 29, 30) 

 designated Coluber milieus as the type of the genus, consequent^ previously to 

 P.oie, and as not even the latter himself, under the International Code, could undo 

 the previous action of Fitzinger, the name Lycodon must be retained in the sense 

 adopted by Boulenger.
