In general form and size and colouring this species somewhat re- 

 sembles our //. Orbitulus, from which it may be at once distinguished 

 by its narrow, scarcely reflected, dark-coloured lip. 'The ground- 

 colour of this species is usually whitish, or lemon-yeUow, and the 

 varieties are banded with dark green, gray, nearly black, and light 

 green, and the columellar lip is commonly purplish black, with a 

 crimson tinge. The following is an indication of the varieties : — 



a. Apex dull red ; ground-colour lemon-yellow ; antesutural band 

 dark green ; post-circumferential band light greenish gray ; columellar 

 lip purplish black, vrith rose-coloured edges ; columellar circumference 

 green. From Banqui, in the province of North Ilocos. 



b. Apex dull red ; ground-colour pale lemon-yeUow ; antesutural 

 band dark gree^ ; post- circumferential band greenish gray close to 

 the broad circumferential band, which is reddish black ; columella 

 purplish black, its circumference green. From Banqui. 



c. Apex dull red ; ground-colour pale lemon-yellow ; antesutural 

 band green, darker in front ; post-circumferential band greenish gray, 

 also darker in front ; columella and its immediate circumference pur- 

 plish black, around which is a rather broad green band. From Sinait. 

 Found on the leaves of trees. 



d. Apex dull red; ground-colour lemon-yellow; antesutural band 

 broad, dark green, composed of several narrow bands, next to which 

 is a broad, pale, greenish gray band ; circumferential band dark green, 

 nearly black ; columella purplish red, its circumference with a broad 

 green band. From Banqui. 



e. Apex dull pale red; ground-colour pale lemon-yellow: ante- 

 sutural band broad, dark green ; post-circumferential band very broad, 

 greenish gray, vrith a very narrow nearly black band in front ; then 

 comes a narrow band of the ground-colour, and the remainder is 

 green to the circumference of the columella, which is blackish ; the
