beautiful simplicity of the Linnean binomial system, with the 

 original authors' names appended for ever, and I quite approve ot 

 Jenning's practice of using the original author's name without any 

 brackets to signify that the species is not now in its original genus. 

 I observe that there is quite a considerable revolt against the 

 tyranny of the strict application of the rules of priority, as we have 

 felt it in recent years.

Notes on the Species. 



Echiniscus crassipinosus Murray (?) (9). Plate VI, figs. 2a, 2b. 



Variety. — Agreeing with the type in the arrangement of the 

 plates and processes, the paired plates show a character which was 

 not observed in the original examples. Each plate of the pairs is 

 divided into three dotted bands, separated by two plain bands with- 

 out dots. 



Habitat. — Kikuyu, British East Africa (coll. A. Allan). 



Z^. Echiniscus sp. Plate VI, figs. 4a-4c. 



Description. — Length 200//,; red; plates 9, two median, two 

 pairs. Lateral processes : a, seta ; b, c, d, e, short fine setae spring- 

 ing from small papillae. Fringe of short teeth on fourth legs ; all 

 claws without barbs. Dorsal processes : over c and d at each side 

 a straight stout spine, which is roughish. The dots on the plates 

 are small, regular, and pellucid, and appear to be depressed papillae.
