Rhynchocephalia. 
llatteria is, in the opinion of Prof. Peters, an aberrant form of the Agamcb^ 
resembling Amhlyrhynchus in the membranous symphysis of the mandible 
and in the apparent absence of copulatory organs. Sitzgsber. Qes. nat. 
Freund. Berl. 1870, p. 64. [The Recorder has had an opportunity of showing 
to Prof. Peters the copulatory organs in a less than half-grown example of 
Amhlyrhynchus^ 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 te Iguana.']
