100 HALIOTIS. 



H. cruenta Reeve, Conch. Icon., 1. 15, f. 56. — Sows. Thes. Conch., 

 f. 63, 101.— Weixkauff, Conchyl. Cab., t. 24, f. 4. 



Closely allied to H. pustulata but at once separated from that by 

 its fine spiral striation. There are traces of pustules on some of the 

 wider striae on the earlier portion of the whorl. Reeve gives the 

 locality " New Zealand" ; but it has not been found there by resi- 

 dent collectors. Hutton says : " perhaps the same as rugosoplicata" 

 — a complete misapprehension, as it has no affinities whatever with 

 that shell. 



H. ancile Reeve. PI. 5, fig. 23. 



Shell ovate, uniformly convex, faintly spirally nodulously stri- 

 ated, nodules sometimes nearly obscure, interrupted ; perforations 

 numerous, small, eight open ; olive-green, nodules and around the 

 spire coppery-rose-red. 



A uniform, convex shell, striated with faint interrupted, irregular, 

 nodulous striae of a coppery-rose hue, with the perforations small 

 and numerous. (Reeve.) 



Habitat unknown. 



H. ancile Reeve, Conch. Icon., f. 71. — Sowerby, Thes. Conch., f. 

 65. — Weixkauff, Conchyl ien Cab., t. 28, f. 3. 



Closely allied to H. pustulata, perhaps not specifically distinct. 



H. pustulata Reeve. PI. 11, fig. 57 ; pi. 23, figs. 48, 49, 50, 51, 



56, 57, 58. 



Shell oblong, depressed, the distance of apex from margin about 

 one-seventh to one-eighth the length of the shell. Sculptured with 

 coarse unequal spiral cords separated by deep interstitial grooves, 

 usually more or less obviously radiately plicate in the vicinity of 

 the spire, the penultimate and beginning of the last whorl usually 

 having series of small pustules along the spiral cords ; growth-striae 

 very close and fine ; perforations generally 6. 



The right side is almost a straight line from its junction with the 

 spire to the termination of the row of holes ; the left margin is 

 arched ; the body is less convex than in most specimens of H. varia. 

 The coloration of the typical form is a dark irregular mottling of 

 brown, green and sometimes whitish ; but many specimens are a rich 

 chestnut marbled with yellow or white, or are light yellowish-brown 

 with reddish-chestnut spots. None of the shells before me have the 

 broad radiating flames characteristic of H. varia. The surface has 

 numerous strong unecpaal spiral cords, more or less undulating and
