distinguished it as a new species, he continued : — " Le Dr. Dybowski 

 l'a rencontre en nombre assez considerable sur le fleuve Ussuri sous 

 le 48° de lat. bor., ou un certain nombre est reste pour l'hiver. II 

 dit dans sa lettre du Novembre 1873, qu'elles se nourrissent pendant 

 cette saison de Salmo leucomcenis, qui y ont peri en quantite apres 

 avoir fraye, et leurs cadavres se sont accumules dans la glace ou ont 

 ete rejete's sur sa surface. II a envoye une peau d'un male tue le 17 

 Octobre 1873." 



An extract was read from a letter of Dr. W. Peters, Foreign 

 Member, in which it was stated that he had lately received from 

 Panama a specimen of the very rare and curious Lizard described 

 and figured in the Society's ' Proceedings' for 1863 (p. 154, pi. xxi.) 

 as Poriodogaster grayi, Smith ; so that this would appear to be the 

 true patria of this species, and not Lower California, as suggested 

 by Dr. Gray. 



An extract was read from a letter of Dr. J. Hector, C.M.Z.S., 

 pointing out an error in his paper on Cnemiornis calcitrans (P. Z. S. 

 1873, p. 763). The words "weight" and "bulk" over the two 

 columns in the table at the bottom of the page have been acci- 

 dentally transposed, similar bulks of bone having been compared, 

 which produce varying weights. 



The table should stand as follows : — 



Bulk. Weight. 



1 . Cnemiornis 10 244 



2. Ocydromus 10 210 



3. Stringops 10 187 



A.Nestor 10 131 



6. Hieracidea 10 126 



showing that the humerus of Cnemiornis is by far the heaviest. 



Prof. Newton exhibited and made remarks on two letters, the 

 property of J. B. Wilmot, Esq., M.D., written from Mauritius 

 18 June, 1628, by Emanuel Altham, referring to a live Dodo whic h 

 he was then sending to England. 



A communication was read from Dr. J. E. Gray, F.R.S., containing 

 a list of the species of Feline Animals (Felidce). 



Mr. G. Busk, F.R.S., presented two communications from Mr. 

 W. C. M'Intosh, of Murthly, Perthshire. The first of these was 

 entitled, " Contributions to our knowledge of the British Annelida ;" 

 and the second contained the first portion of an account of the Anne- 

 lida collected during the 'Porcupine' Expeditions of 1869 and 1870. 



These papers will be printed in the Society's 'Transactions.' 



The following papers were read :— -
