Island of Music ar y Dutch New Guinea. 371 



Xesta citrina, Linn. 



Two varieties, one with lemon-colourel ground with a 

 dark brown band on periphery of last whorl, the other dark 

 brown above with a still darker band at periphery of last 

 whorl, which is sharply contrasted by a white band below, 

 the remainder of underside being of a glassy white colour. 



Chloritis cheratomorpha, Tapp.-Canefri. 



Planispira (Cristigibba) dolen?, Fulton, sp. n. 



Shell subcircular, with deep umbilicus about 2 mm. wide 

 at upper part, white, smooth and polished, subtransparent, 

 with a very narrow reddish-brown band at suture of upper 

 whorls descending to edge of peristome and situate on last 

 whorl just a little above the periphery (where it is about 

 1 mm. in width) ; spire almost flat, apex being slightly 

 depressed ; whorls 4£, last descending about 2 mm. ; peri- 

 stome white, moderately expanded, margins joined by thin 

 callus ; aperture snbovate, very oblique; constriction at rear 

 of peristome very slight. 



Maj. diam. 21^, alt. 10 mm. 



Hob. Muswar Island, Geelvink Bay, Dutch New Guinea. 



Similar in form to wahnesi, Fulton, but flatter and thinner, 

 with smaller aperture and different coloration. 



Thinner and more circular in form than cormcu\im } H. & J. ; 

 the aperture is smaller and the peristome not so widely 

 expanded. Compared with papuana, Mlldff., and semirasa, 

 Marts., it is larger, not so flat, and not nearly so strongly 

 constricted at rear of aperture. 



Papuina antiqua, Ad. & Rve. ( = !eonardi } Canefri) [ = Jwr- 

 deri, Sowb.). 



This is a veiy variable species in form and coloration ; the 

 two specimens received from Muswar Island are of a uniform 

 light brown or fawn colour. 



Papuina grata, Michelin, var. magna, Fulton, var. nov. 



Maj. diam. 33, alt. 25 mm. 



The Muswar Island specimens are much larger than typical 

 grata and densely covered with hairs. 



I am not sure that the pilose character of this species has 

 been recorded before ; the hairs are evidently easily rubbed off. 



Papuina hero, Smith.
