Conus asphaltodes     (Beets, 1953)





The holotype is 54 (+ ?) mm long. The spire is more turreted than in C. petrolei (see albove), its stepped whorls being excavated and separated by a keel lying close to the anterior suture. The steps are much more inclined than in C. petrolei and the profile of the spire is different too. The apical portion is damaged but it may be stated that the early whoris bear a granulate keel which becomes smooth on the younger whorls. The whorls of the spire are covered with numerous delicate spiral striae. The growthlines are well-developed and more concave than in C. petrolei, the deepest part of the sinus being more distant from the posterior suture than in C. petrolei.

Tine body-whorl is plumper than in C. petrolei and in addition not constricted anteriorly. The columella is not concave as in C. petrolei and its basal portion shows but little curvation. In front of the keel runs a conspicuous spiral and anteriorly of this, numerous delicate spiral striations.

The latter are wider on the anterior portion of the body-whorl (though more delicate than in C. petrolei) and separated by conspicuous grooves. According to the growth-lines, the outer lip is protruding slightly more than in C. petrolei (1).


The type is from Waisioe (coll. N.H.B.).
