This man- dibular dentition points to affinity with the Lycodonts, near which I would place Pseudoxyrliopus in the system, with the following definition:— Maxillary teeth 16 to 18, the two posterior strongly enlarged and separated from the preceding by an interspace ; anterior mandibular teeth much larger than the posterior and increasing in size to the fifth, sixth, or eighth. Head scarcely distinct from neck; eye small, with round pupil. Body cylindrical; scales smooth, without pits, in 17 to 25 rows. Tail rather short; subcaudals all or part in two rows. ^5^W (^^MjljlJjli!ll0^^ ^^^. Figure showing the dentition of:—A. P. mia'ops; B. P. quinqtie- li7ieatus ; C. P. imennce. Five species are known, which differ in the following characters :— A. Scales in 25 rows; frontal as broad as long; rostral just visible from above; two labials entering the eye; ventrals 207-225; subcaudals 45 P. micrcps, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original London, Taylor and Francis, Ltd
