Ziphius australis ; nevertheless the row of teeth standing above 

 the gums was perfectly formed ; and, secondly, the specimen of 

 ZipJdus novce zealandice, of which the Canterbury Museum pos- 

 sessses a complete skeleton, was an aged female and obtained in the 

 flesh, but did not show the least trace of any row of small teeth 

 above the gums. 



1 have examined carefully the gums of the new species in both jaws, 

 where no teeth were visible, but without the least success, no hidden 

 teeth being in existence anywhere. 



Finally I propose to designate this new Cetacean by the specific 

 name q{ grayi in memory of the late Dr. J. E. Gray, to whom New 

 Zealand is so much indebted for his contributioDS towards the better 

 knowledge of its natural history. 



Conclusion. 



In summing up the evidence which the three skulls under review 

 present to us, the following points maybe accepted as fully* esta- 

 bhshed : — 



1st. That there exists a Ziphioid Whale in the New- Zealand 

 seas which possesses a mandibular tooth at the posterior edge of the 

 symphysis, either hidden below the gum or standing conspicuously 

 above it, according to age or sex. 



2nd. That the skull of one of the sexes (probably the female) is 

 longer but narrower and lower than that of the opposite (probably 

 the male) sex^the latter possessing also a large triangular compressed 

 tooth rising above the gum, which in the other (probably female) 

 sex is much smaller and almost hidden below the gum. 



,3rd. That both sexes possess permanently in the upper jaw a row 

 of small conical teeth with the apex slightly incurved, which, althougli 

 only rooted in the gums, have to perform important functions in tlie 

 nourishing-process of the animal.

The Rev. ,1. E. Semper, of St. Lucia, who has already done so 

 much to make us acquainted with the ornithology of that island, 

 has lately forwarded to me a third collection of birds, which I have 

 now the pleasure of exhibiting. It contains examples of eight 

 species not included in my two former articles on this subject*, 

 and among them two specimens of a very remarkable form, which
