332 Dr. C. Pollonera on new 



The tliree new species of Trichotoxon about to be described 

 sliouldj in my opinion, constitute a new subgenus, for which 

 I propose tiie name Dendkotoxon. 



This subgenus differs from typical Trichotoxon in possess- 

 ing (as is also the case in Dendrolimax) on the upper 

 extremity of the epiphallum a true^ though very small, 

 jlagellum instead of the calcareous gland. 



Dr. Simroth employs the term " kalk-sac " for both the 

 true flagellum, situated on the lower side of the epiphallum, 

 and also for the calcareous gland on the upj)er side ; person- 

 ally I prefer to give different names to these two characters, 

 especially as in some species of the Urocyclidce there is an 

 absence of the calcareous gland inside the flagellum. 



Trichotoxon {Dendrotoxon) Icempi, sp. n, 

 (PI. Vlll. figs. 5, 6, 7.) 



Clypeus postice rotundatiis, profunde sulcatus et valide rugosus ; 

 brunneo-iuscus, summitate rugarum sordide albidus ; apertura 

 pulmonea distincte antemediana ; apertura pallialis aiigiista sed 

 distincta. Dorsum valide sed obtuse carinatiim, granulosum, 

 lateraliter oblique sulcatum ; colore terreo, macnlis rotundatis, 

 amplis, evanescentibus, griseo-nigrescenti conspersum et rcinutis- 

 sime albido punctatum. Pedis margo externus transverse 

 sulcatus et minutissime albido-punctatus. Solea Isevis, unicolor, 

 zonse laterales leviter transverse sulcatse. 



Longit. dorsi mill. 35; clypei 22; soleae 62. 



Hcd). Between the Igembi Hills and Nyeri (Eobin Kemp). 



The light blotches on the shield, the small scattered spots 

 upon the back, the carina, and the margin of the foot are 

 produced by a calcareous concretion identical with that 

 j)roducing the large light blotches on Dendrolimax. 



The reproductive organ (tig. 6) shows an atrium ter- 

 minating above in two rounded points and enclosing four 

 extraordinaiily long, pitted, pointed, and slightly recurved 

 darts (fig. 7). Tlie lower flagellum is very long; the 

 upper very small, preventing a view of the calcareous gland, 

 which perhaps is either altogether absent or is very much 

 reduced in size.

 (PI. Vlll. figs. 8, 9, 10, & 11.) 



T. sat robustum, coriaceo unicolor, anticetantum pallidior. Clypeus 

 postice rotuudatus, longitudinaliter valide rugosus, apertura 

 palliali angustissima, apertura pulmouea vix antemediana.
