text, as are al^ th^py'awia of two other new 'Species of Delphinus, the 

 "' j5e//)/i. /<l»girSrz5^d Delph. acutus. In this gemis Mr. Gray proposes 

 several new subgenera with the following characters : Delph iNus ; 

 " Capite globoso ; rostro depresso, capite longiote ; dentes^cylindrici, 

 " curvati ;" o^ this Delph. Delphis may be regarded as the type : Gram- 

 y^ PUS ; " capite globoso ; rostro depresso, longitudine capitis; detites 

 ** cylindrici, curvati ;" typical species Delph. (?r(^jows, Linn.-t Belu- 

 ga ; " capite depresso, attenuate^ ; rostro longitudine capitis in eodem 

 ► *' piano ;" formed by the Delph. leucOs, Pall. :' and Phoc^na ; " ca- 

 " pite globoso ;'fostro csljjjite breviore; dentes compressi spathiilati ;" 

 comprehending the Delph. Phocmna, Liiin;, 



The Reptilia illustrated are the Testudo Bellii, a new species, the 

 ^ animal and shell of which are figured : the Chamceleones Brookesiana, 

 Gray, dilepis. Leach, and Tigris, Kuhl, all of which are now repre- • 

 sented foB*the first time : and ihe Phyllodactylus pulcher, the type of a 

 new genus of Geckotidce which is thus characterized : Phyllodacty- 

 lus; **;Digiti 5 — 5, graciles, compressi, uHimo articulo squama lata 

 *' foliacea longitudipaliter fissa, ungues recurvatos vagiiMite; pori femo- 

 *' rails nuUi ; cauda^t^lindrici subtus serie squamarum majorum." 



Among the Mollusba many new species are characterized, especially 

 in the genus Chiton ; and the information in this department is rendered 

 peculiarly valuable by the^ descriptions cf the animals, hitherto doubtful 

 oi*imperfectly kn6l^, of several* i?iteresting genera, including M'ltra, 

 Tornatella, and Sigaretus. Appended to the latter is an indication of 

 all the species observed by Mr. Gra;^- as belonging to that ^us. The 

 animal of Vermetm is al^o described from ih^Verm. maximus, a species 

 hitherto unnoticed, which constitutes the second of the group, and fiiUy 

 establishes the correctness of Ai^anson's description, and of the conse- 

 quent location of the genus by Lamarck. The only new genus proposed 

 is among the Venerid(s, Glauconome, " Testa equivalvis ; umbones 

 " subanteriores ; periostraca tenuis dura : dente&^cardinales tres in utra- 

 " que valva, laterales nulli : impressio siphonalis longissima :" the spe- 

 cies on^^vhich it is founded, the Glauc. Chinensis, being described as 

 new. It is an inhabitant of fresh water. 



Of Cirrhipeda four are figured as tk^ types of so many genera pro-
