iqO'i Dipsas infrenalis Rosen. Ann". Mag. Nat. Hist., (7) IJ: 180. Type-locality: None given. 

 1960 Dipsas infrenalis — Peters, Misc. Publ. Mus. Zool. Univ. Mich., 114: 214. 



Distribution: Unknown.

DIPSAS SUBAEOUALIS Fischer 



1880 Dipsas subaequalis Fischer, Arch, fur Naturg., 46; 224, pi. 5» figs. 18-21. Type-locality: 

 Unl<nown. 



Distribution: Unknown. 



Comment: Boulenger, Cat. Sn. Brit. Mus., 3, I856, 88, suggested that this might be an Imantodes , 

 but the coloration as described is so different from any other species in that genus that this 

 seems a most Improbable generic assignment. 



DROMICUS AMAZONICUS Dunn 



1522 Dromicus amazonicus Dunn, Proc. Biol. Soc. Washington, 35' 215. Type-locality: Santarem, Brazil. 



Distribution: Known only from type locality. 



Comment: The generic assignment of this species is very questionable. The holotype must be 

 re-examined in the light of recent interpretations of generic lines. 



ERYTHROLAMPRUS MENTAL IS Werner 



1509 Erythrolamprus mental is Werner, Mitt. Naturhist. Mus. Hamburg, 26: 238. Type-locality: 

 Guatemala. 



Distribution: Unknown. Stuart does not mention the species in his Guatemalan checklist (1563). 



Comment: This taxon has been placed in Con i ophanes by various authors and in Rhad i naea by Bailey, 

 Pap. Mich. Acad. Sci., Arts, Letters, 24, I938 (l539), 5, but all such actions have been 

 tentative, awaiting re-examination of the type. This specimen was destroyed during World War 

 II, and the taxon may never be properly allocated. 



HELICOPS LEPRIEURI I MOESTA Jan 



I865 [ Hel icops Lepr ieur i i ] van. moesta Jan, Arch. Zool. Anat. Fis., 3: 253. Type-locality: None 

 G i ven. 



Distribution: Unknown. 



Comment; Boulenger, Cat. Sn. Brit. Mus., 1, 1893» '^11 > tentatively synonymized this variety with 

 Hel icops modestus . but this cannot be determined without question from Jan's description. The 

 type, which has not yet been located, must be re-examined for proper allocation of the taxon. 



HERPETODRYAS ANNECTENS Werner 



1924 Herpetodryas annectens Werner. Sitz. Ma th. -Na turwi ss. Kl. Akad. Wiss. Wien, Abt. 1, 133' 33- 



Type-locality: Presumed to be Brazil by Werner, since it was in bottle with two other snakes 

 from that country. 



Distribution: Unknown. 



Comment: Amaral, Mem. Inst. Butaiitan, 4, I929, 14, stated that this was not Brazilian, not neotrop- 

 ical, and wrong in the generic assignment. Amaral did not attempt to assign it elsewhere.
