the male. By means of this process Mr. Daniell believes the female 

 to be capable of giving greater tension to the pouch formed of that 

 membrane for the reception of the young in the act of parturition. 



November 25. — A Letter was read, addressed to the Secretary by 

 Keith E. Abbott, Esq., and dated Trebizond, June 20, 1834. It re- 

 ferred to a collection of skins of Birds made by the writer in his 

 immediate neighbourhood, and presented by him to the Society. 

 The number of species contained in the collection is twenty, one 

 only of which was comprised among those previously transmitted by 

 Mr. Keith Abbott, and exhibited to the Society at its Meeting on 

 June 24, 1834. Mr. Abbott states that he proposes to continue the 

 collection of such zoological subjects as he can procure in the neigh- 

 bourhood of Trebizond, for the purpose of transmitting them to the 

 Society. 



The Bird-skins presented by Mr. Keith Abbott were exhibited, 

 and Mr. Gould, at the request of the Chairman, brought them seve- 

 rally under the notice of the Meeting, observing on each of them as 

 regarded its geographical distribution. The exhibition was regarded 

 as a continuation of that which took place on June 24, (Lond. and 

 Edinb. Phil. Mag., vol. v. p. 314.) and comprised the following spe- 

 cies not then enumerated, making in the whole fifty-three species 

 observed in the vicinity of Trebizond. 



Falco Tinnunculus, Linn., Otus vulgaris, Cuv., Sylvia Rubecula, 

 Linn., EmberizaCia,hmn., Alauda arvensis, hirm., Corvus Monedula, 

 Linn., Picus medius,ljmn., Ardea Garzetta, lArin., Scolopax major ^ 

 Linn., T ring a variabilis, Charadrius Pluvialis, Linn., Charadrius Hi- 

 mantopus, Linn., Anas Querquedula, Linn., Anas Fuligula, Linn., 

 Clangula vulgaris, Flem., Mergus Albellus, hinn., Podiceps cristatus . 

 Particulars of the geographical distribution of all these species, as 

 given by Mr. Gould, will be found in the ' Proceedings.' 



Mr. Gray exhibited a specimen of a Reptile from New South 

 Wales, which he regarded as constituting the type of a new genus 

 nearly related to Bipes, Latr. He characterized it under the name of 



LlALIS. 



Caput elongatum, fronte piano, squamis parvis subimbricatis ves- 

 titum : irides lineares, verticales : aures oblongse, conspicuae. 



Corpus subcylindricum, attenuatum : squamis dorsalibus ovatis, con- 

 vexis, laevibus; ventralium seriebus duabusintermediismajoribus. 



Pedes duo, postici, obsoleti, acuti, ad basin 2 — 3-squamati. 



Anus subposticus : squama prteanales parvae ; pori subanales utrin- 

 que quatuor per paria dispositi. 



This genus is very nearly allied to Pygopus, Merr., but may be 

 readily distinguished from it by the characters above given. In 

 Pygopus the head is short, more rounded in front, and covered with 

 regular shields : the pupil is subcircular : the feet are broad, ovate, 

 blunt, and covered with three rows of scales : the vent has five large 

 oblong scales in front of it : and the subanal pores form a continu- 

 ous series.
