6 MB. AND MBS. PECKHAM ON [May 7, 



Leopold to issue stringent orders for the protection of this 

 remarkable creature. Its flesh is said to be excellent eating, and 

 there is no reason why an attempt should not be made to domesti- 

 cate it. 



" At the present time the known habitat of the Okapi (as this 

 animal is called by the natives) consists of the forests of the Ituri 

 and the western banks of the Semliki in the Congo Free State, 

 and the adjoining district of Mboga in the Uganda Protectorate." 



The following papers were read : — 



1. On Spiders of the Family Attidce found in Jamaica. 

 By G. W. Peckham and E. G. Peckham l . 



[Received April 12, 1901.] 



(Plates II.-IV. 2 ) 



Most of the Spiders described in this paper were collected 

 by us some years ago. We have also received some specimens 

 from Mr. T. D. A. Cockerell, and from Mr. Taylor of Kingston. 

 Other Attida? that have been described from Jamaica are : — 

 Marptusa melanognaihus Lucas ; Saitis anna Cockerell, ' Canadian 

 Entomologist,' p. 343, 1894 ; Anoka peckhamii, Cockerell, ' Journal 

 of Institute of Jamaica,' vol. ii. p. 221, 1893 ; Zygoballus suavis 

 Peckham, " Spiders of the Homalattus Group," Occ. Papers 

 Nat. Hist. Soc. of Wisconsin, vol. ii. p. 173. Anoka moneagua 

 Peckham, " Spiders of the Marptusa Group," Occ. Papers 

 Nat. Hist. Soc. of Wisconsin, vol. ii. p. 127, 1894, is identical 

 with Anoka peckhamii Cockerell. The thirteen species now 

 described probably give a fair idea of the Attid fauna of the 

 island. The genera are like those of Central and North America, 

 excepting Cybele, which we have from St. Vincent, and Nilakaniha, 

 which is new.
