190 PARTULA, TAHITI. 



Anaa, a low coral island, as its habitat. Having resided 

 about five months on that island, and searched all parts for 

 shells, I did not find a single Partula there, or on any other 

 low coral island. Though neither Pfeiffer nor Reeve allude 

 to a parietal tooth, it is very frequently present." (Garrett) .

 pressly umbilicated ; whorls 6, smooth, somewhat rounded, lip 

 and columella broadly reflected. Pink, red-brow*n towards

Fig. 4 is a copy of Reeve's. The examples before me are 

 the form sent out as turricula by Pease. They are all sinis- 

 tral, elongate, glossy, varying from chestnut-tinted yellow to 

 pale yellow with light green streaks on the last two whorls, 

 those preceding rose-tinted, the shade deepening to the apex. 

 The lip is white in the paler shells, rose-tinted in the darker. 

 Measurements vary from length 22, diam. 12.1, aperture 10.9 

 mm., to 19, 11, 9.8 mm. just three-fourths of the adult shells 

 seen have a parietal tooth. Garrett writes: "Reeve's rubes- 

 cens is abundant in Papinoo, and occurs sparingly in all the 

 valleys as far as the southeast end of the island. Like ama- 

 bilis it cannot be separated from the sinistral turreted ota- 

 heitana, inhabiting Fautaua. It is always sinistral, never 

 banded, and, though usually of a reddish tint, is frequently 

 straw-yellow or fulvous, with or without a reddish or pinky 

 apex. The lip is white or pinky flesh-color. Though de- 

 scribed as edentate, some have a small parietal tooth. Reeve 

 gave no locality, and Pfeiffer erroneously cites the Marquesas 

 as its habitat."
