During I'.MO Mr. A. Allan, of Kikuyu, British Easl Africa, was 

 good enough to send frequently large parcels of moss, properly 



collected and dried, in which there were found numerous Bdelloid 

 Rotifers, including several interesting and some new species. 



Sir Philip Brock lehurst, on a hunting tour in the same region, 

 kindly collected moss on a mountain (iOOO feet high. 



Mr. Allan's collections were from different localities and alti- 

 tudes, of which he sent details in letters, but unfortunately this 

 useful information cannot be used to discriminate the species from 

 the different altitudes, as, owing to postal delays and irregularities, 

 we often could not tell to which of several parcels an explanatory 

 letter referred. 



The species in this list appear under several unfamiliar generic 

 names, which require a word of explanation. These genera, which 

 include many old friends among the species, are adopted from Mr. 

 Bryce's recently published Classification of the Bdelloids (J). The 

 new genera represented in our list are three in number. 



Plev/retra includes 4-toed Bdelloids (formerly Callidin.v) which 

 have a stiff leathery trunk, deeply plicate, the folds on the ventral 

 side transverse. (Species alpium, brycei, humerosa.) 



Mniobia includes those species (formerly Callidinse) which have 

 no distinct toes, but a discoid sucker instead. (Species tetraodon, 

 scarlatina, symbiotica, etc.) 



Habrotrocha includes all the pellet-making Callidinse, except 

 one or two very aberrant forms, which have been made into dis- 

 tinct genera. (Species constricta, lata, perforata, etc.) 



The genera Philodina and Gallidina remain as before, but 

 restricted by the separation of the groups defined above, and of 

 some others which are not represented in our list. The genus 

 Rotifer is scarcely affected, but is more strictly defined, and receives 

 a few viviparous species, previously regarded as Callidinse. 



In all descriptions as many of the principal dimensions as 

 possible are given. These are not meant as bard and fast data., of 

 specific importance. The species vary somewhat in size. They 

 are intended to give the relative proportions with sufficient accu- 

 racy to enable one who knows the Bdelloids well to construct a 

 figure which would give some idea of the appearance if the original 

 drawing were lost. 



The species in Sir Philip Brocklehurst's collection are not 

 numerous — there were only four species of Rotifera and a few 

 Tardigrada. Nevertheless, two of the Rotifera are new to science. 

 One of these is known to Mr. Bryce, and will be described by him. 

 The other I name after the finder. These facts indicate the assist- 

 ance which can be rendered to science by sportsmen, when they 

 are thoughtful enough amid the excitements of the chase to pocket 

 a little moss as occasion offers in those remote regions to which 

 they penetrate.
