1871.] MR. P. L. SCLATER ON CERTAIN PELICANS. 631 



completely destroyed ; but, thanks to the energy and skill of our 

 articulator Mr. Henry Barnes, it has been so far restored that a tole- 

 rably correct idea may be formed of its original shape. The lower 

 jaw was very much broken ; there appeared no teeth above the gum ; 

 but after removing the flesh I found a very curious looking tooth in 

 its alveolus, the points of which penetrated the bone on either side. 

 The number of cenicals is three anchylosed and four free. Nine 

 pairs of ribs, and a very small pair which appear to have no attach- 

 ment. Five of the ribs join on to the sternum, which consists of 

 five pieces. The lumbars and caudals amount to twenty-nine, with 

 nine V-bones attached to them. The pectoral limb is of moderate 

 size, bearing four fingers, with five, five, four, and three joints re- 

 spectively. The number of carpal bones is six." 



Photographs of the skeleton, which accompanied Mr. Krefft's 

 letter, were exhibited. 



Professor Flower stated that, as far as could be ascertained from 

 the photographs, the skull of the new specimen agreed so closely 

 with that described by Gray under the name of Ziphius layardii 

 (P. Z. S. I860, p. 358) that he believed that they should be referred 

 to the same species, the differences of development of the teeth being 

 probably due to the influence of sex or age. He trusted that before 

 long Mr. Krefft would furnish the Society with an accurate and de- 

 tailed description of this very interesting skeleton. 



Professor Flower, F.R.S., read a memoir on the classification of 

 the Ziphioid Whales {Ziphiince), which he regarded as a subfamily 

 of the Physeteridce*, and in which he proposed to recognize four 

 genera, namely Hyperoodon, Ziphius, Mesoplodon, and Berardius. 

 To this was added a complete description of a skeleton of Berardius 

 arnouxi, which had lately been received from New Zealand by the 

 Museum of the Royal College of Surgeons, through Dr. J. Elaast, 

 F.R.S.

In May, 1868, I had the honour of reading before the Society 

 some notes on the Pelicans, principally based upon the observation 

 of the specimens of these birds living in the Society's collection \.
