348 Mr. C. O. Waterhouse on new 



Genus Scala (Klein, 1753), G. Humphrey, 1797. 



Type = Turbo scalar is, Linnaeus. 



= Cyclostoma, Lamarck, 1799. 

 = Scalaria, Lamarck, 1801. 



It is trusted that these observations may lead to greater 

 accuracy in the future when dealing with the literature and the 

 types connected with the history of these genera.

Uroxys brevis, sp. n. 



Breviter oblongus, convexus, nitidus, nigro-piceus ; capite lrevi, 

 fronte carina transversa instructs, clypeo apice bidentato ; thorace 

 transverse-, convexo, fere kevi, lateribus leviter arcuatis, laevissime 

 bisinuatis ; elytris thorace perparum angustioribus, quam latitu- 

 dine paullo brevioribus, tenuiter striatis, striis liBvibus, interstitiis 

 fere planis, lasvibus ; pygidio lsevi ; tibiis anticis obtuse triden- 

 tatis, ad apicem truncatis ; mesosterno utrinque punetis nounullis 

 notato, a metasterno linea fortiter angulata diviso ; femoribus 

 piceis.

This species is closely allied to U. Batesi, Harold, but is 

 still shorter. The clypeus has the teeth shorter and more 

 triangular. The thorax has the sides less abruptly turned 

 inwards at the anterior angles; the lateral impression is elon- 

 gate, but does not run off into a line at each end. The elytra 

 have the striaa finer and apparently impunctate. The line 

 dividing the mesosternum from the metasternum is strongly 

 angular, having an angle of about 110°, leaving the meso- 

 sternum very long ; whereas in U. Batesi the line is bent at 

 an angle of about 80°, reaches forward almost to the front 

 of the mesosternum, and has the apex itself rounded. 



Uroxys terminalis, sp. n. 

 Leviter convexus, nitidus, piceo-niger ; capite fere kevi, inter oculos
