In Helemano and Waialua district, the northwestern limits 

 of pulclierrima^ the same forms occur. Those of Kalaikoa do 

 not differ noticeably. In Ahonui part of the lots examine 1 

 are like those of "AVahiawa.' In others there are many whit- 

 ish shells with a gamboge tint, with or without dark lines. 

 Also a lot of shells varying from chestnut to sulphur-tinged 

 yellow, with sutural band only, many of them stouter in form 

 than typical pulclierrima. Length 18.5, diam. 11.5 mm. 

 These lots are from the Gulick collection. PI. 31, fig. 14 is 

 from low in Helenrano, coll. by Spalding, 



Judging from the description and figure of A. melanostoma 

 Xewc., as well as from specimens received from him, it is a 

 synonym of pulclierrima, being based upon a somewhat dif- 

 ferent color form from that of Swainson, though occurring 

 with the typical color- form in AVahiawa district. Newcomb's 

 locality, Ewa, refers to the district, which takes in the ex- 

 treme southeastern part of the range of pulcherrima. The 

 original description follows. 



A. melanostoma Newc. (pi. 29, fig. 7, reproduction of ori- 

 ginal figure). "Shell dextral, polished, solid conical; whorls 

 6, plano-convex, slightly margined above ; suture moderate, 

 accompanied with a black revolving band. Aperture sub- 

 ovate; lip black, thickened within. Columella short, brown- 

 ish-red, terminating abruptly in a strong plait or tuberosity. 

 Color yellowish or umber, with or without transverse brown 

 lines. Length fourteen-twentieths, diam. seven-twentieths 

 inch. Ewa, Oahu : (Neivcomb).
