lleloderma suspectum , Cope. Weir, Mitchell, & Reichert have made 
experiments on the physiological action of Heloderm-poisou. They find 
that this Lizard’s mouth-liquids are highly poisonous, killing frogs, 
pigeons, and rabbits in a few minutes ; also that the physiological action 
of the poison is quite different from that of snake-poison ; the latter kills 
essentially by paralyzing the respiratory centre, the former by paralyzing 
the heart. Medical News, Feb. 10, 1883. [Not seen by Recorder; cf. 
Science, i. p. 372.]

be near the Lacertidce , forming, with Lepidopkyma , A. Dum., and Crico-
