296 FAUNA OF NEW ZEALAND. 



ON THE FOSSIL SHELLS FROM NEW ZEALAND. By 

 J. E. GRAY, Esq. 



Under Pectunculus, I have referred to some fossil shells 

 which Dr. Sinclair brought with him from the East Cape of the 

 Northern Island : since that notice was printed, Dr. Dieffenbach has 

 shown me some specimens from the same locality, from Parenga- 

 renga in the Northern Island, from Kawia and Waingaroa, and 

 from Chatham Island. 



The specimens from the East Cape, in addition to the Pectun- 

 culi brought by Dr. Sinclair, contain a Natica ; some fragments of 

 a large Dentalium ; a specimen of Pyrula, like P. Smithii, but 

 smaller ; many specimens of a Fusus, and of anAncillariavfiih a 

 very callous apex. All these specimens so much resemble in form 

 and condition, and in the character of the matrix, the shells found at 

 Bognor, in Sussex, that they might easily be mistaken for speci- 

 mens coming from that locality. 



The specimens from Chatham Island consist of the two lower 

 valves of a large Ostrea with a very large area, allied to 0. gigantea, 

 or 0. expansa, and having the calcareous deposit of the abductor 

 muscle destroyed by fossilization in the same manner as the speci- 

 men of O. expansa figured by Mr. Sowerby, t. 238, f. 1, and pf 

 several specimens of the convex valve of a vesicular Gryphcea near 

 G. Columba. They appear to belong to the greensand formation. 



The specimens from Parenga-renga are in a conglomerate, and 

 all consist of fragments of a species of Turritella, with smooth finely 

 spirally striated flat whorls, the animal of which fills up the cavity 

 of the upper whorl of the shell. 



The specimens from Kawia and Waingaroa consist of a very 

 thick ponderous Ostrea, three specimens of Terebratula, a Pecten 

 like P. Japonica, and a Spatangus. They are in a limestone 

 matrix. 



Vespertilio luberculatus, p. 181. I have just received two speci- 

 mens of this bat : it is a new genus, differing from Embalonura, 

 Kuhl, and Urocryptus, Temm., in having only two large cutting 

 teeth in the middle of the upper jaw ; the fur is close, erect, dark 

 brown, with minute white tips to the hair; the under surface is 

 paler; the face has a series of short, rigid, black bristles round the 

 base of the muzzle, the wings near the body and bones of the limbs 

 are thickened and transversely grooved ; the tragus is elongate, 

 subulate. It may be called Mystacina tuberculata. J. E. GRAY.
