28 PROF. T. J. PARKER ON CARCHARODON RONDELETII. [Jan. 18, 



Specimen D. — Female, 17 ft. (about 5 metres) long. The second 

 specimen referred to in the preceding paragraph was canght about 

 a fortnight later than the first, and was also brought entire to 

 Dunedin for exhibition. The funds of the museum would not allow 

 of its purchase, and indeed my assistants were at the time so fully 

 occupied with the preparation of the larger specimen, that it would 

 have been impossible for them to undertake a second task of similar 

 magnitude ; so that all I could do was to be present when, on the 

 third day after capture, the viscera were removed, and to make some 

 notes on those organs which were too much decomposed in the 

 former specimen. 



Specimen E. — Foetus (female), 55 cm. long. For this I am 

 indebted to Mr. E. P. Ramsay, F.L.S., Curator of the Australian 

 Museum, Sydney. 



I may also mention that, as I am informed by my friend Prof. A. 

 P. Thomas, a specimen of Carcharodon, fully 30 ft. long, was caught 

 at Auckland a few months ago. It would seem, therefore, that in 

 spite of its apparent scarcity in museums, Carcharodon rondeletii 

 must be a tolerably common species in the Southern Seas. 



1. External Characters. 



As the small specimen described by Smith, iu his ' Zoology of 

 South Africa,' appears to be the only one of which careful measure- 

 ments have been taken, it seems advisible to give a fairly complete 

 series of measurements of specimen C, the largest which has come 

 under my notice.
