Species 0/ Urocyclidse/zro/?* British East Africa. 333 



Dorsum rugosum, lateraliter sulcis parum profunrlis sulcatum, 

 per totum longitudinera carinatum ; carina valida, obtusa, postice 

 tortuosa. Solea unicolor, zona mediana granulosa, laterales 

 transverse sulcatco. 

 Longit. dorsi mill. Si ; clypei 26 ; solese 72. 



Hah. Between the Igembi Hills and Nyeri {Robin Kemp). 



Differing from the preceding species in its larger size, 

 twisted carina, less forwardly placed pulmonary orifice, and 

 by the total absence of all spots, either light or dark. 



The reproductive organ (fig. 8) differs from that of 

 T. kempi in the shape of the atrium, which terminates above 

 in two more lengthened, divergent, and less rounded points. 

 I'he neck of the bursa copulatrix is less long, more pitted, 

 ttTid terminated by a cylindrical arch which is wanting in 

 T. kempi. The penis is less twisted and of a different sliape. 

 The lower flagellum (fig. 11) is shorter, less pitted, and 

 greatly swollen by the rounded eminences of a tissue 

 which is more transparent than that of the flagellum ; it ends 

 on its free side in a small oval sacj of the same nature as the 

 lateral eminences. The upper flagellum (fig. 10) is very 

 small and permits a view of the white calcareous gland, 

 which is situated on the interior of its base ; in the atrium 

 1 found five darts, much shorter and broader than those of 

 T. hmpi (fig. 9), and I believe this to be the first case, 

 up to the present time, in which an uneven number of darts 

 has been noticed. 



Trichotoxon [Dendrotoxo7i)heniens{s, sp. n. 

 (PL Vlll. figs. 3, 4.) 



T. sat parvulum, ochraceo-aurantiaco unicolor, antice pallide 

 ochraceum. Clypeus postice rotundatus, granulosus ; apertura 

 palliali angnsta ; apertura pulmonea distincte postmcdiaua. 

 Dorsum obtuse carinatum, rugoso-granulosum ; lateialiter sulcis 

 obliquis, parum profundis, sulcatum. Solea, medio pallida, zonis 

 lateralibus pallide bruuneis, transverse sulcatis. 



Long, dorsi miU. 17 ; clypei 13 ; soleae 50. 



Hah. Mt. Kenia, at an altitude of 9000-10,000 feet {Rohin 

 Kemp) . 



Differing from the two preceding species in its smaller 

 size, in its granular and not longitudinally furrowed shield, 

 on the posterior half of which is situated the pulmonary- 

 orifice, in the colour of the shield and dorsal surface, which 

 is of a pale orange-ochre, disappearing on the posterior 

 portion of the animal, and in the brownish colour of the 

 lateral zones on the side.
