carrying one apical and one lateral seta. Mandibles with the masticatory part 

 divided into a number of delicate llattened teeth, pulp nniarticulate. but exhibiting 

 one or '2 small lateral lobes. Maxilla' and maxillipeds of normal structure. Na- 

 tatory leg* comparatively short, with both rami densely spinulose at the edges. 

 and more or less incurved, carrying at the tip long and slender setfiB, outer ramua 

 with the spine> of the outer edge \ery long, but without any setse inside, inner 

 ruiiius biurticulate: 1st pair oidy slightly dillering from the :> succeeding ones. 

 Last pair of legs with tin- distal joint ruther coarse and. like the inner expansion

 reduced in size. Ovisac single. 



lii Hi-irk*. - -This genus was rather insufficiently characterised by Boeck. 

 and for this reason was not recognised by succeeding authors. Boeck himself 

 referred to this genus 2 species which are evidently not congeneric, the one, 

 /.'. longicauddta, having indeed turned out to be a true Cl<'to<li -. described above 

 ax ( 7, (ml,* li,niiii-iniil>if,is. The other species, K. nirtici(il<i. which of course must 

 be regarded as the type of the present genus, has recently been redescribed by 

 Th. Scott under another name us a species of the same genus. On the other 

 hand. Prof. Brady describes, under the name of C/rfml,^ prnjihu/ni. a species which 

 is evidently congeneric with the type of Boeck's genus Eiihi/ilfu^nini. Finally, 

 the form referred by the same author to the latter genus, E. curvatum, is very 

 different from both these genera, constituting the type of a particular genus. It 

 appeal's from this, that great confusion prevails among authors as regards the 

 present genus, the exact characters of which I have tried to draw up in the above 

 diagnosis. 3 well-detined species referable to this genus will be described below.
