OO COCHLITOMA. 



margined. A specimen from near Port Elizabeth measures, 

 length 74, diam. 39, apert. 40 mm. It is not always so solid 

 as would be gathered from Krauss' remarks. Fig. 11 of pi. 

 16 is a copy of the type figure ; fig. 10 another specimen ; and 

 pi. 27, fig. 36 is copied from Reeve's figure of a large Cum- 

 ingian specimen, which has also been figured by Pfeiffer in 

 the Conchylien Cabinet. 



Reeve, by some error or misunderstanding, printed the name 

 "kransii" in his first description and illustration, but he 

 makes it clear whom he intended to honor by the name, and 

 subsequent authors including Reeve himself have accepted 

 the rectification made by Dr. Pfeiffer. 



"This species resembles A. zebra in shape, but differs in the 

 much stronger shell, and the white and predominating dark 

 brown coloration, which often is variable, as I have shells with 

 the last whorl uniform dark brown. It has 7 whorls, all 

 smooth, and crenulate at the suture only. It is generally 2.75 

 inches long, 1.5 wide [about 69x38 mm.], only one specimen 

 among the great number I have collected is 3 inches long and 

 has 8 whorls " (Krauss). 



"Of four specimens brought from Cape Colony by Dr. 

 Penther, the largest measured 122 mm. long and 51 mm. wide, 

 aperture 63x33 mm." (Sturany 1 ).

"M:c j : -ather solid and heavy, ovate, acuminate above or 

 in the < ! section of the apex. The colors are about equally 

 divided, and consequently the ground color may be termed 

 either volute or dark-brown; in the former case it would be 

 streaked and blotched with brown and in the latter with 

 white. The streaking and blotching are very irregular, but 

 decidedly display a tendency for an oblique direction parallel 

 with the lines of growth. Whorls iy 2 rather convex, and 

 ornamented over the entire surface with narrow, elongate 

 granules, which like the coloring also follow the direction of 

 the incremental lines and stride. The last whorl is not very 

 ventricose, but extends or is produced some distance below the 

 truncated end of the columella. The aperture is about, as
