A NEW CEEEUS FROM THE WEST INDIES. 

 By Ove Paulsen. 



In working out the Cactacece of the formerly Danish islands 

 St. Croix, St. Thomas, and St. Jan in the West Indies, I have 

 had to deal with fairly good plant-material preserved in alcohol. A 

 ke}'' and list will be published later. 



The following description is of a species which I believe to be new. 

 American botanists are collecting material for a comprehensive treat- 

 ment of the Cactacecs, and it will be useful to publish any novelties, in 

 order that they may be included in the final treatment :

Planta parva repens radicans ramis articulatis articulis triangu-

 bi*evi-tomentos8e, aculeis radialibus ca. 10 centralibus 1-2, omnibus 

 subsequalibus rigide setaceis ca. 3 mm. longis. Flores et fructus 

 absunt.

BIBLIOaRAPHICAL NOTES. 

 LXXIII. Maund's "The Botanist" (1836-1842?). 



The recent acquisition by the Department of Botany of a copy 

 of the first number of The Botanist in the original wrapper, which 

 gives information as to its publication and scheme not easily accessible, 

 led me to examine the work somewhat closely with results which, if 

 not of the first imjiortance, are, I think, not altogether without 

 interest. As is usual in such cases, one thing led to another, and the 

 investigation proved somewhat tedious to myself, as I fear the follow- 

 ing account of the results may appear to my readei-s, in which case I 

 will anticijjate criticism by offering my apologies in advance. 



I. The Dates. 



The first point of interest in connection with the work concerns 

 the date of publication, which has been variously stated : thus, Pritzel
