Conus (Monteiroconus) neugeboreni (Hoernes & Auinger, 1879)

 

 

 

 

 

Descrizione  (2)

 

Description: Moderately large shell of pyriform shape. Low conical spire with pointed apex; spire whorls deeply concave in adapical half, forming a convex bulge in abapical part; smooth, suture narrow and regular. Shoulder rounded; last whorl moderately convex above maximum diameter, strongly constricted below; subsutural flexure shallow, moderately curved, moderately asymmetrical. Aperture narrow adapically, widening towards moderately narrow and long canal. Base with narrow, widely-spaced, convex spiral cords; siphonal fasciole very weak; inner lip narrow, slightly twisted.

Colour pattern under UV light consisting of numerous, densely spaced spirals of dashes covering the last whorl; the blotches on the shoulder indicated by Hoernes & Auinger (1879, pl. 1 fig. 5) are a misinterpretation or are not visible any more.

 

Discussion  (2).

At first sight, this species might be considered synonym with Pseudonoduloconus austriacus ( Hoernes & Auinger, 1879) , due to its pyriform shape. It differs, however, in the narrower, deeply concave spire whorls, the regular suture, the rounded shoulder and the even more pronounced constriction of the base. The aperture is adapically narrower, as is the siphonal canal. The position of maximum diameter is placed lower, resulting in a Ficus -like outline and lastly M. neugeboreni ( Hoernes & Auinger, 1879) lacks the subobsolete tubercles on the spire whorls seen in P. austriacus . As the fig-shaped outline is also atypical for Monteiroconus , this generic placement is tentative.

Paleoenvironment. No information is available; shallow water elements are frequently found transported into deep marine settings at Lăpugiu de Sus.
