throat and the subcolumellar laraella is obsolete below There is a long palatal 

 plica and a short upper united with the lunella. Sutural plicae and a lamella ful- 

 crans are developed. The clausilium is notched on the palatal side of the pro- 

 jecting apex and excised on the eoluinellar side of the filament). Typus C. hed- 

 leyi n. 



Diceratoptyx n. sect. Phaedusae; Pilsbry 1904 Pr. Phil. p. 836 (the glossy 

 shell is zaptychoid, the superior lamella developed, inferior laraella receding, 

 calloused below. Subcolumellar lamella risiug high on the palatal wall, dilated 

 in a lateral position. Upper palatal plica very long, an extremely short lunella 

 descending from near its inner end. Lamella fulcrans et paralella and sutural 

 plicae are developed. Clausilium deeply excised as usual at the filament, and 

 with a deep notch excavated near the apex on the palatal side). Typus D. cla- 

 doptyx n. 



Luchuphaedusa nov. subg. Phaedusae; Pilsbry 1901 Pr. Phil. p. 411. (Shell 

 fusiform, the right margin of the peristome usually crenate, outer margin excavated 

 above to form a sinulus, superior lamella marginal, projecting, continuous with 

 the long spiral lamella; inferior lamella strongly spiral within, calloused below; 

 subcolumellar lamella dilated adjacent to the very long and strong lower present; 

 principal plica long; upper palatal plica developed, sometimes coalescent with the 

 lunella. Clausilium wide, truncated or notched distally, and with a thickened 

 lobe or finger-like process on the columellar side of the apex Standing at nearly 

 a right angle with the body of the plate). — Typus ?. Erste Art: Th. callistochila 

 n. — Cfr. id. Pr Phil p. 816 



Nesiophaedusa n. sect. Phaedusae; Pilsbry 1904 Pr. Phil. p. 815 (Phaedusoid 

 Clausiliae of normal contour, with a tendency to weak interlamellar plication; 

 inferior lamella prominent in the mouth, spirally ascending, thick, sometimes 

 indistincly douhled within; palatal armature lateral, the lunella arising from the 

 middle of a strong lower palatal plica, and curving inward above in a short 

 upper palatal plica. Clausilium very convex on the palatal side, tapering distally 

 to a blunt, thickened apex, chanelled on the outer face). — Typus: Clausilia 

 bernardii Pfr. 



Oophaedusa n. sect Phaedusa; Pilsbry 1904 Pr. Phil. p. 820 (the clausilium 

 is well curved, spatulate, with a thick rib near the columellar side of the distal 

 half, continued and finger-like at the apex; the shell is short, oblong, of few 

 whorls (6 - 67 2 iu the species known), the summit very obtuse, entire. Superior 

 continuous with the spiral lamella. Inferior lamella strongly spiral within, bifid 

 below. Upper and lower palatal plicae long, the latter united with an oblique 

 lunella). Typus: Claus, ophidoön n. 



Urocoptidae. 



Pilsbry giebt in vol. 15 von Tryons Manual die Monographie der Familie, 

 welche er in zwei Unterfamilien scheidet, Eucalodiinae vom Festland, und Uro- 

 coptinae von den westindischen Inseln und Süd-Florida; eine Ausnahme bildet nur 

 Archegocoptis von Haiti. 



Archegocoptis n. gen. Eucalodiinarum für A. eximia Pfr. und A. crenatum 

 Weinl. & Mrts., beide von West-Haiti, anatomisch von allen Westindiern ver- 

 schieden; Pilsbry Manual 1903 p. 301
