Anolis velifer Cuvier. The female of this species would fall in the " genus" 



Euprhtis Fit'i.= Dactyloa Gray. 

 Typhlops sp. 



Chilabothrus inornatus Dura. Bibr. Only found elsewhere in Jamaica. 

 Alsophis sancticrucis Cope (=.4. melanichnus Cope).

 Philad. 1862, p. 344. 



This species does not belong to Peltaphryne, but to a genus which I now 

 name. It differs from the former in the existence of an additional superficial 

 arch of the skull, w^iich passes from the mastoid region behind the auricular 

 meatus, thus enclosing the latter, and causing it to be a mere foramen perfo- 

 rating a shield of bone. This is the only genus of living Batrachia in which 

 the external ear is thus completed behind. It is a tendency of Peltaphryne 

 carried to its highest extreme. 



Cuba ; found by Prof. Poey. 



Lystris brachyops Cope, sp. et gen. nor. Cystignatbidarum. 



Tribe Pleurodenue, same group as Pleurodema, differing only from that genus 

 in the presence of two strong shovel-like metatarsals, as in the genus Systoma. 



Its characters are, therefore : cranium with a fronto-parietal fontanelle ; xi- 

 phisternum an osseous st3ie, with furcate cartilage disc. Vomerine and max- 

 illary teeth well developed ; a large inguinal gland ; two metatarsal shovels. 



It differs from Gomphobates in its fontanelle and vomerine teeth, but is in- 

 termediate between this genus and Pleurodema, showing that the tribes Plen- 

 rodemae and Cystignathi should be closely approximated. It differs onlj', so 

 far as we know the characters, from Eupemphix Steind , in the presence of a 

 well-developed dentition in adults as well as young. The other characters of 

 Eupemphix are not yet known, or whether it is nearer this genus or Gompho- 

 bates. Steindachner's second species of Eupemphix I would refer here, and 

 call it Lystris f u s c om ac ul a t u s . Name of the genus from Aur^poy, a 

 trowel. 



Char, specificu-s. — Vomerine teeth in two short oblique series directed for- 

 wards between the nares, about as far from the latter as from each other. 

 Tongue a flat oval, one-third free. Head broad, occiput slightly swollen, can- 

 liius rostralis straight, obtuse, convergent; loreal region vertical plane. Di- 

 ameter of bony orbit equal length of muzzle ; the latter contracted, elevated, 

 rounded in profile ; nostrils nearer end than orbit. Membranum tympani one- 

 third orbit. Ostia large as nares. Males only with a subgular sac, with large 

 lateral slits. Limbs short, stout; the heel barely reaching the tympanum. 

 Toes quite short, free, without dermal margins. No tarsal median tubercle or 

 fold. Inguinal gland large subovate. Skin smooth above and below ; a few 

 ill-defined warts on the back. Lengths of fingers 3 — 2 — 1 — 4.
