Carcinus maenas, Pennant. 



Mr. Wood Mason exhibited a specimen of Carcinus mcenas. 

 Pennant, taken in 1866 or 1867 at Point de Galle, Ceylon, by Dr. 

 J. Anderson. Comparison of this specimen with those from the 

 Mediterranean lately received from Prof. Cornalia, of Milan, had en- 

 abled him to be sure of the correctness of his previous identification 

 from the published figures and descriptions. The species appeared 

 to have an exceedingly wide distribution, being found in abundance 

 on the shores of the British Isles and of the United States, whence 

 it extends to the Arctic Sea, and on all the Mediterranean coasts ; it 

 has also been recorded by Heller from Rio Janeiro ; and specimens 

 will doubtless ultimately be met with in the Red Sea. — Proceedings 

 of the Asiatic Society of Bengal, Xovember 1873. 



Cetacea of the North Sea and the Baltic. 



Professor Malm, in his * Zoological Observations,' gives a compara- 

 tive account of fifteen specimens of the common porpoise (Phoccena 

 Linncei) occurring in the Baltic. He describes and figures a gravid 

 female, and young, and mentions the peculiarities of each specimen. 

 He observes that the small tubercles on the front edge of the dorsal 

 fin, on which Dr. Gray has established Phoccena tuhercidifera, occur 

 very rarely among these animals ; he only found it in one specimen 

 (no. 13) out of the whole of the paale and female specimens which 

 he examined ; and therefore he thinks this species is still doubtful. 



Professor Mobius gives an account of a male and female grey 

 grampus {Gramjjus griseus), which were taken on the 17th and 19th 

 of February 1871 on the west coast of Holstein, between the Elbe 

 and Eider. I beHeve this is the first time that this southern species, 

 which sometimes visits the south coast of England, has been recorded 

 as found so far north. 



Professor Mobius records the occurrence of the following species 

 in the Little Belt : — 



Phoccena communis, F. Cuvier. 



Pseudorca crassidens, Gray. November 24, 1861. 



Delphinus tursio, Otho Fabricius. June 1870. 



Lagenorhynchus albirostris, Gray. Winter 1851-52. 



Hyperoodon rosfratum, Pontop. December 3, 1807..

On some Extinct Types of Horned Perissodactyles. By Edward D. 

 Cope, of Philadelphia, Penn. 



It is well known that the type of Mammalia of the present period, 

 which is preeminently characterized by the presence of osseous horns, 

 is that of the Artiodactyla Ruminaiitia. At the meeting of the As- 

 sociation of last year, held at Dubuque, I announced that the horned 

 mammals of our Eocene period were most nearly allied to the Pro- 

 boscidians. I now wish to record the fact (as I believe, for the first 

 time) that the Perissodactyles of the intermediate formation of the
