instructa; labrum tenue, arcuatum; columella recta, incrassata, ad 

 basim abrupte truncata. Long. 2, cliam. r5mni. 



Sal. — On orange-trees. 



Under the microscope the surface has a minutely frosted appearance, 

 produced by excessively fine spiral striation. 



23. Cyclotus (Psetjdoctclophoeus) Lombockensis, n.sp. 



PI. II, rig. 18. 



Testa globoso-turbinata, anguste iimbilicata, rufescens, lineis albis 

 undulatis sutura radiantibus picta, et supra anfractum ultimum plus 

 minus obscure albo notata ; spira conoidea, ad apicem subobtusa ; 

 anfractus 4:\-5, perconvexi, sutura profunda sejuncti, apicales nigro- 

 pnrpurei, ultimus antice leviter descendens, incrementi lineis obliquis 

 striis spiralibus decussatis sculptus ; apertura rufo-fusca, albo vaiie - 

 gata ; peristoma duplex, continuum, subincrassatum, pallide cameum, 

 margine externo interno magis prominente, subexpanso, sed baud 

 reflexo. Diam. maj. 14, min. 11 mm. ; alt. 13 mm. 



Hah. — Einjani Peak, 2,500 feet. 



This species belongs to the same group as C. politus, Sby,, 

 C. fulminatus, Martens, etc. 



24. Eegistoma OBLiaTJTJM, n.sp. PI. II, rigs. 19, 20. 

 Testa oblonga, compressa, irregularis, subpellucida vel pallide 



rufescens, polita ; anfractus 5 ; superiores quatuor regulariter accre- 

 scentes, vix convexiusculi, spiram brevem conicam formantes, ultimus 

 valde oblique distortus, supra aperturam planiusculus, conspicue 

 oblique descendens, sed prope labrum subito ascendens ; sutura 

 pellucide anguste marginata ; apertura parva, circularis ; peristoma 

 leviter incrassatum, albidum, margine columellari minute inciso. 

 Diam. 3'6, alt. 6mm. 



J«5.— Sumbawa, 2,500-5,000 feet (Doherty) ; Lombock, 4,000 feet 

 (Everett). 



This species is distorted like certain forms of Streptaxis, the spire 

 being regular and the body-whorl remarkably oblique, whilst the 

 penultimate bulges out on the left side above the last. Callianella 

 Wallacei (Pfr.) is very similar in form. 



25. DrPLOMMATESTA LoM:BOCE:Ejsrsis, n.sp. PI. II, Fig. 21. 



Testa sinistrorsa, imperforata, pupoidea, cornea, pellucida, nitida ; 

 anfractus 6, perconvexi, apicales duo laeves, cseteri lamellis tenuibus 

 obliquis arcuatis subdistantibus (in anfractu penultimo circiter 20) 

 instructi, ultimus penultimum latitudine sequans, supra aperturam 

 contractus ; apertura late auriformis ; peristoma leviter incrassatum, 

 expansum, continuum, margine superiore appresso, columellari intus 

 prominente, vel rotunde subdentato. Long. 3'5, diam. 1*6 mm. 

 Apertura cum perist. \b longa. 



Hah. — Lombock (W. Doherty). 



The last lamella on the body-whorl is well developed and situated 

 close to the peristome, which consequently has a duplex appearance.
