DESCRIPTIONS OF SIX NEW SPECIES OF LAND-SHELLS FROM 



ANN AM. 



By Edgar A. Smith, F.Z.S., &c. 



Mead May I2lh, 1893. 



The specimens about to be described formed part of the collection 

 of the late M. Emile Eudel, and were obtained by Mr. Fulton when 

 that collection was sold a few months ago. With the exception of the 

 two species of Ci/clophorus all were collected by M. Eudel himself in 

 1890. A note accompanying the specimens reads as follows: — 

 " Recoltes vivants dans les Montagues boitees du Huyen de Tri-phuoc, 

 Province Biuh-dinh, An-nam." 



Both the Rhyssota and the Hadra are very fine species, and the 

 Amphidromm is remarkable for the peculiar varix on the back of 

 the body-whorl. 



The two species of Cyclopliorus were collected on the " Collines du 

 Tillage de Yung-chao, Bong-can." It is with considerable hesitation 

 that I venture to describe new species of this genus, notorious for the 

 uncertainty of many of the species already published. 



Maceochlamts projiiscita. 



Testa dcpressa, orbicularis, parum elata, anguste perforata, supra 

 fusco cornea, vix nitida, infra pallida, albo-cornea, polita ; anfractus 

 65^ Icnte accrescentes, convexiusculi, incrementi lineis ad suturam 

 confertis striisque spiralibus minutis numerosissimis supra sculpti, 

 ultimus ad peripheriam obsolete angulatus, infra baud concentrice 

 striatus ; spira depresse conica, ad apicem obtusa, pallida ; apertura 

 oblique lunata, cseruleo-albida ; peristoma tenuissimum, margine 

 columellari leviter incrassato, supra umbilicum breviter reflexo. 

 Diam. maj. 31 mm., min. 28, alt. 19. Apertura 16 lata, 14 alta. 

 Hah. — Annam. 



Macrochlamijs promiscna , n.sp. 



This species is remarkable for the contrast in colour and sculpture 

 of the upper and under surfaces. The fine puckering at the suture, 

 caused by very numerous arcuate and oblique lines of growth, is also 

 peculiar.
