Crocodilus niger. Note on a specimen from the Bonny River, 4 feet long,
by Gray, Ann. & Mag. 1870, vi. p. 427.
RHYNCHOCEPHALIA.
Hatteria is, in the opinion of Prof. Peters, an aberrant form of the Agamce,
resembling Amblyrhynchus in the membranous symphysis of the mandible
and in the apparent absence of copulatory organs. Sitzgsber. Ges. nat.
Freund. Berl. 1870, p. 54. [The Recorder has had an opportunity of showing
to Prof. Peters the copulatory organs in a less than half-grown example of
Amblyrhynchus, and has found them also since in a young Oreocephalus. In
the adult they must be quite as large as in Iguana. Indeed it would have
been a matter of surprise if these organs had been absent in the Galapagos
Lizards, which are truly Iguanoid genera, and most closely allied to Iguana.]

Ophiops. A number of species belonging to this or closely allied genera

in comparing and critically examining typical examples, it may be sufficient
to refer to the papers in which they are described: Jerdon, Pr. As. Soc.
