text, as are also the crania of two other new species of Drlphinus, the 

 Delph. longirostris and Delph. acutus. In this genus Mr. Gray proposes 

 several new subgenera with the following characters : Delphinus ; 

 " Capite globose ; rostro depresso, capita longiore ; dentes cylindrici, 

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

 pus ; " capite globoso ; rostro depresso, longitudine capitis ; dentes 

 " cylindrici, curvati ;" typical species Z)eZp^. Cr amp w?, Linn. : Belu- 

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

 " piano ;" formed by the Delph. leucas, Pall. : and Phoc^NA ; " ca- 

 " pite globoso ; rostro capite breviore ; dentes compressi spathulati ;" 

 comprehending the Delph. Phoccena, Linn. 



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 for the first time : and the Phyllodactylus pulcher, the type of a 

 new genus of Geckotidce which is thus characterized : Phyllodacty- 

 lus ; " Digiti 5 — 5, graciles, compressi, ultimo articulo squama lata 

 " foliacea longitudinaliter fiss&, ungues recurvatos vaginante; pori femo- 

 " rales nulli ; cauda cylindrici subtus serie squamarum majorum." 



Among the Mollusca many new species are characterized, especially 

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

 peculiarly valuable by the descriptions of the animals, hitherto doubtful 

 or imperfectly known, of several interesting genera, including M'ltra, 

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

 all the species observed by Mr. Gray as belonging to that genus. The 

 animal of Fermetiis is also described from the Verm, maximus, a species 

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

 establishes the correctness of Adanson's description, and of the conse- 

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

 is among the Veneridce, Glauconome, " Testa equivalvis ; umbones 

 " subanteriores ; periostraca tenuis dura : dentes cardinales tres in utra- 

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

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

 new. It is an inhabitant of fresh water. 



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