Anops Kingu. An. corpore suprd Jiisco , infrh albido.

Hab. in America Australi. 



This genus is referrible to the Amphishcenidče , with which it 

 .agrees in general form, in the structure and arrangement of the 

 scales, the concealed eyes and ears, and the short obtuse tail. 

 Frona the other genera of the family it is distinguished by the form 

 of its rostrum and of its singular compressed frontai plate, which 

 considerably resembles that which characterizes the genus Ty- 

 pJilops. 



The second of these ReptUes belongs to the family ScincidcE, It 

 is characterized by Mr. Bell as follovvs : 



Lerista. 



Caput scutatum ; palpebrce nuUse; aures sub cute latentes. 

 Corpus gracile ; squamce laeves seąuales. 



Pedes quatuor : anteriores exigui, brevissimj, didactyli ; poste- 

 riores longiores, tridactyli. 



Anus simplex, semicircularis ; pori prceanales etjemorales nulli. 



Lerista lfneata. Ler. teneo-viridcscens, subtils pallidior,; 

 lineis binis dorsalibus et binis lateralibus nigris. 



Hab. in Australia. 



This new genus of Schicidce agrees vvith Gymnophthalmus, Merr., 

 and Jbiepkarus, Fitzing., in the absence of eyehds ; but differs 

 from both in the number of its toes : the former having 4-5, and 

 the latter 5-5, while Lerista has only 2-3. In addition to this dif- 

 ference in the structure of the feet, it is remarkably distinguished 

 by the want of external ears, and by its elongated and anguiform 

 body ; characters in which it agrees with Saiplios, Gray. The last- 

 named genus, hovvever, possesses eyelids, and difters also in the 

 number of its toes from Lerista. 



Mr. Bell also read a paper, entitled " Observations on the Nect 

 ofthe three-toed Sloth, Bradypus tridactylus, Linn , demonstrating 

 that this Aniraal possesses only the Normai Number of Cervical 

 Vertebra." 



By all preceding anatomistssince the days of Hermann the num- 

 ber ofthe cervical vertebrcB in t-he three-toed Sloth has been consi- 

 dered to be nine ; and the animal has conseąuently been regarded 

 as deviating in this respect from the other Mammalia, in vvhich class 

 seven is tl>e normai nuaiber of these parts, — a number which exists
