ACHATINELLA ELEGANS AND FUSCOBASIS 169 



brown band above the periphery, sometimes bisected by a 

 dark line ; suture white-bordered ; summit light yellowish. 

 Aperture pale blue within, the lip thickened within, with a 

 narrowly but distinctly expanded, acute 'brown edge. It is 

 also narrowly bordered with brown outside. The strong cohi- 

 mellar fold is white. Length 21, diam. 12 mm. or smaller, 

 length 19.2, diam. 11 to 12 mm. 



Punaluu (Gulick). 



This race approaches A. obliqua somewhat, but seems 

 nearer elegans. It has the maroon-brown or purplish-brown 

 layer overlaid with a streaked white film, giving various tints 

 difficult to name, but near dutch blue, deep madder blue and 

 slate purple of Ridgway's Color Standards. The whitish or 

 pale-brown band above the periphery is nearly always prrs- 

 ent, and often more conspicuous than in fig. lla. Sometimes 

 (fig. lla) there is a thin yellow cuticle, but usually none. 

 One lot of 8 from Newcomb, without habitat, consists of sinis- 

 tral shells. Another lot from Gulick has 3 dextral shells in a 

 total of 22. It is probably extinct now. 



This form was named for Charles M. Wheatley, the well- 

 known collector of Phoenixville, Pennsylvania, 



11 A. ivheatleyi" was mentioned twice by Newcomb: in 

 Annals of the Lyceum of Natural History of New York, vi, 

 p. 147, October, 1855, where he says " A. wheatleyi Nob. is 

 A. vidua Pfeiffer, " and again in the same volume, p. 324, 

 September, 1858, " The A. vidua Pfr., which I had supposed 

 was my manuscript A. ivheatleyi, I find in Mus. Cuming to be 

 a somewhat worn and faded specimen of this species " [A. 

 cvata] . As no characters were ever assigned to A. wheatleyi 

 except by implication in the above remarks, we have no 

 option but to accept Newcomb 's published statement of what 

 his A. ivheatleyi was, even though he sent out specimens 1 of 

 what we are now calling u'heatleyana as A. wheatleyi. 



SERIES OF A. FUSCOBASIS. 



Ovate shells, smaller than those of the bulimoides series; 

 mainly sinistral, never marked with green, and having some 

 resemblance to the casta series of Achatinellastrum. They 

 are almost entirely shells of the high ridges and peaks.
