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 

 1 propose the name Dendrotoxon. 



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 upper side ; person- 

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

 especially as in some si)ecies of the UrocycUdce there is an 

 absence of the calcareous "land inside the flagellum. 



Trichotoxon {Dendrotoxon) kempi, sp. n. 

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



Clypeus postice rotundatus, profunde sulcatus et valide rugosus ; 

 brunnco-tuscus, summitate rugarum sordide albidus ; apertura 

 pulinonea distincte antcmediana ; apertura pallialis aiigusta sed 

 distincta. Dorsum valide sed obtuse carinatum, granulosum, 

 lateraliter oblique sulcatum ; colore terreo, maculis rotundatis, 

 amplis, cvancsceutibus, grisco-nigrescenti conspersum et minutis- 

 sime albido punctatum. Pedis margo esternus transverse 

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

 zoDffi laterales leviter transverse sulcata?. 



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



Hah. Between the Igembi Hills and Kyeri (BoMn 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)ioducing the large light blotches on DendroJima.r. 



The reproductive organ (fig. 6) sho-ws an atrium ter- 

 minating above in two rounded points and enclosing four 

 extraordinarily long, pitted, pointed, and slightly recurved 

 darts (fig. 7). The lower tlagellum 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. 



Trichotoxon (Dendrotoxon) iretitoni, sp. n. 

 (PI. Vlll. figs. 8, 0, 10, &11.) 



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

 postice rotundatus, longitudinaliter valide rugosus. apertura 

 palliali augustissima, apertura pulmonea vix antomediana.
