Of this species, which inhabits the jungle in troops of from five to 

 twenty, Dr. Cantor gives a detailed description, with an account of 

 its habits both wild and in a state of captivity, and details of the dis- 

 section of a young male, particularly as regards the stomach, which 

 presented, with some modifications, the same highly developed struc- 

 ture as the other species of the genus which have been examined. 

 It appears to be most nearly allied to Semn. maurus, Horsf. 



Semn. cristatus, Horsf., is also a native of Prince of Wales's Island 

 and the opposite part of the Malayan Peninsula. Dr. Cantor com- 

 pares it with the foregoing species and gives some particulars of its 

 habits in captivity, and of the dissection of a young female. 



The paper was illustrated by figures of Semn. halonifer and of its 

 stomach and caecum, and of the head of Semn. cristatus, its stomach 

 and gall-bladder.

Read the commencement of a paper, entitled " Some Observations 

 upon the Structure of two new species of Hectocotyle parasitic upon 

 Tremoctopus violaceus, Delle Chiaje, and Argonauta Aryo, L. ; with 

 an exposition of the hypothesis that these Hectocotyle are the males 

 of the Cephalopoda on which they are found." By Albert Kolliker, 

 Professor of Physiology and Comparative Anatomy in the University 

 of Zurich. Communicated by R. Brown, Esq., V.P.L.S.

 sula." By Theodore Cantor, M.D., Civil Surgeon, Prince of Wales's 

 Island. Communicated by Dr. Horsfield, V.P.L.S.

This species, of which Dr. Cantor gives a detailed description, ap- 

 pears, he states, to form an intermediate link between Chrys^eus su- 

 matrensis. Ham. Smith, and Chrys. javanicus of the same author. But 

 in the former of these two species all the feet are pentadactylous ; 

 neither of them has the feet hairy ; and the second tubercular tooth 

 of the lower jaw is present in both, but absent in Chrys. soccatus. A 

 pair of the last-named species were captured in Malacca and brought 

 to Prince of Wales's Island, where they died a few days after their 

 arrival. Dr. Cantor states, on the authority of Wm. Lewis, Esq., 

 Assistant Resident Councillor at Penang, that they hunt deer and 

 antelopes in troops of from thirty to fifty or more. He gives also 

 some particulars of their anatomy, and a figure of the species.
