(4) Natividad Island, off the south end of Cerros. A shell col- 

 lected by Anthony and sent me alive by Dr. Dall (pi. XV, fig. 12) is 

 banded and streaked profusely with purplish-brown. The embryo 

 is distinctly wrinkled and the inner whorls following are somewhat 

 granulated; lip narrow. Alt. 21, diam. 23.8 mm., with 5| whorls. 

 The genitalia of this individual were figured by me as "areolata" in 

 Proc. A. N. S. Phila., 1898, pi. 1, figs. 6, 7. It certainly has nothing 

 to do with the real areolata, but belongs to the veatchii group of forms. 



(5) Turtle Bay, collected by Hemphill (pi. XV, fig. 9), white or 

 pink-white, immaculate or with a few fleshy dots. Embryonic 

 whorl wrinkled, the rest of the upper surface granulated more or 

 less, lip very narrow. Resembles varieties (2) and (3), except in 

 color. 



(6) Turtle Bay, Hemphill (pi. XV, fig. 8). The white or pale 

 embryonic whorl is nearly smooth (in 8 adult shells examined, no 

 young ones seen); granulation appears weakly on the inner whorls, 

 not on the last one or two. Lip expansion is narrow. The shell is 

 compactly coiled. Bands speckled with white, either numerous, as 

 in fig. 8, or reduced in number and intensity (as in fig. 15). Alt. 20, 

 diam. 23 mm., with 5| whorls. This lot was sent out by Hemphill 

 as "H. areolata var." 



(7) Turtle Bay (pi. XV, fig. 11). Same as No. 6, but white with 

 the coloring of leucanthea, plus some scattered fleshy dots. 



Whether all of the Turtle Bay lots were from one colony or from 

 several is not known. Mr. Hemphill sorted out his Helices into 

 color forms, thereby destroying all evidence as to the composition of 

 the colonies. 



M. veatchii was named in honor of John A. Veatch, who surveyed 

 Cerros Island in search of copper and other minerals in June, July, 

 and August, 1859. By an error or oversight the name was spelled 

 "veitchii" in the original account. 



Micrarionta veatchii canescens (Adams and Reeve). Text fig. 1. 



A series collected by Mr. H. N. Lowe at South Bay, Cerros Island, 

 agrees well with the figures and description of Helix canescens,^ 



5 The original description follows: 



"Helix canescens. Shell globose, nearly covered perforate, opaque white, 

 ornamented with oblique streaks and several interrupted blackish concentric 

 lines and a conspicuous central band, whorls 5, the last rotund-inflated. Aperture 

 lunate-rotund, peristome thickened within, callous in the columellar margin. 

 Hab. Africa. A white globose shell with simple lip banded and minutely sprinkled 

 with black. " (Adams and Reeve, in Zoology of the Voyaqe of H. M. S. Samarana, 

 p. 62, pi. 16, fig. 10, 1848.)
