on the Potto to the Meeting of the British Association in 1850, 

 and a second on the anatomy of the Potto in 1860, in which 

 he refers to a complete monograph of this animal published by 

 him in 1859, in the seventh volume of the Transactions of the 

 Royal Academy of Sciences of the Netherlands (Ortleedkim - 

 dig Ondersock van der Potto van Bosnian door F. A. W. Yan 

 Campen Med. Cand. Uit due Platen Amsterdam. 4to, 77 pp.) 

 Van der Hoeven also details his arrangement of the Lemuridce, 

 published in his " Handbook of Zoology," and refers again to 

 the peculiarity in the Potto, " that some of the spinous pro- 

 cesses of the neck, covered only by a thin corneous epiderm, 

 pierce through the fur-like prickles. They are those of the 

 fifth to the last cervical, and of the first two dorsal vertebras." 

 These projecting processes are evident, Mr Carruthers informs 

 me, in Mr Bennett's specimen, though, probably from its 

 youth, neither so numerous nor so strongly marked as Van 

 der Hoeven describes them. In the two stuffed specimens in 

 the British Museum they cannot be detected, as might have 

 been expected ; as already stated, I could not detect this pecu- 

 liarity in my specimen of the Angwantibo. 



I have been recently favoured with the following explana- 

 tion of the name Angwantibo, horn the Eev. Alexander Robb : 

 — " The name Angwd-ntibo is compound ; the first part is the 

 same as the name of the domestic cat, which the Calabar 

 people call Angwd, or Angwd-mbdna — the ng being a very 

 soft nasal sound. Angwd is probably onomatopoetic, from its 

 resemblance to the sound of the mew or cry of the cat. The 

 meaning of ntibo is unknown to me. The Angwantibo is, 

 therefore, so named, probably because it is supposed to re- 

 semble the cat, either in its cry or in some of its habits. We 

 give this note as a correction of the etymology proposed in 

 the letter at the beginning of the above paper." 



The Secretary reported that as several communications still 

 remained in his hands, which he was anxious should not 

 be allowed to lie over to another Session, he proposed that 

 another meeting of the Society should be held on Wednesday, 

 the 9th of May. This proposal was agreed to, and the 

 Society adjourned.
