PARTULA, NEW GUINEA, TALAUER IS. 305

 115 ; Monogr. ii, p. 68. 



It is not certain that Albers had the same form which 

 Lesson described. P. occidentalis Hedley is evidently a near 

 relative of grisea, but so far as I know, the "Coquille" 

 reached New Guinea only in the west. 



100. P. BULIMOIDES Lesson. 



This Partula is the largest species known to us. It is 10 

 lines long and 7 in diameter. The shell is thick, solid, with 

 the mouth on the right side, large and oval, provided with a 

 thick flange, the umbilicus very open back of the columellar 

 plate adnate to the peristome. The spire is short, conic, ob- 

 tuse at the apex, the whorls parted by a quite deep suture. 

 Last whorl large, ventricose, very finely striate lengthwise. 

 The shell is whitish, but covered with a bright fawn epidermis. 

 The peristome is simple in the young. (Lesson). 



New Guinea (Voy. Coquille). 



Partula bulimoides LESS., Voy. autour du Monde de La 

 Coquille, ZooL, p. 326. 



An unfigured species, not recognized since its description. 

 So far as I know the Coquille landed only at Port Dorey 

 (near Mt. Arfak and the N.-W. cape of Geelvink Bay), and 

 probably this shell came from there. The visit was in July- 

 August, 1824. Hartman, at one time, identified P. canalis 

 as P. bulimoides. From Lesson's description, the shell must 

 be very different from other species of the southwestern 

 Pacific.

The single species from this group is the westermost species 

 of the genus.

"Shell dextral, ovate, rather thin; spire acute, half the 

 length; whorls 5, rounded; suture deeply impressed; body- 

 whorl somewhat inflated; oblique lines of growth fine and 

 crossed by numerous waved spiral strige, compressly umbili-
