The subcaudal counts are as in vcrmicidatnm but somewhat lower than in loveridiici. The sharpness of the characters, as well as the geographical isolation, dem- onstrate that any clinal connection with other subspecies is out the question. Key to the Recognizable Species and Subspecies IN THE Genus Lycophidion Some species which in the past have been rc^ferred to Lycophidion are now attribnted to other genera like Oojiliilosititni, CJioinucIycus ( with which OophilosHuiu has been recently synon- ymized by de Witte, 1963), and Dendrolycus. Tliey are, of course, not in this key, which is iiiodilicd from that of Parker (). L. Apical pits double or more.
