Description.

 

 

 

 

 

 

Remarks.

 

(a) In recent literature (Van Mol, Tursch & Kempf, 1967: 240-242; Rios, 1975: 124) Conus carcellesi is considered a junior synonym of C. clenchi (Martins, 1943).

(b) Coomans, R.G. Moolenbeek and Wils compared two paratypes (fig. 353) and other specimens (figs. 354-355) of C. carcellesi to the Brazilian C. clerii (Reeve, 1843) and C. lemniscatus (Reeve, 1849) (which is a senior synonym of C. clenchi). It is concluded that C. carcellesi is not conspecific with C. lemniscatus, but it may be considered a subspecies of C. clerii.

 

(c) The conchological differences are summarized by Da Motta (1981: 5, figs. 1-3): C. clerii has a turbinate shell with an angulate and carinate shoulder, whereas subspecies carcellesi is biconic with a subangulate and smooth shoulder. In addition C. clerii reaches a larger size (up to 50 mm) than its subspecies carcellesi (to about 30 mm), and the ranges are disjunct (fig. 300) (3).

 


Distribution.

C. clerii s.s. occurs on the Brazilian coast from Bahia to Rio Grande do Sul (fig. 300). The subspecies carcellesi is known to us from Uruguay and the northern coast of Argentina, and reported in the literature (Rios, 1975: 124) from as far south as Puerto Deseado at 48° S (3).

The differences between C. clerii and C. lemniscatus, as originally described, seem mainly due to different patterns: C. clerii has a mostly axial flame pattern; while C. lemniscatus has encircling, articulated narrow brown bands. With enough specimnens, though, these distinctions seem to intergrade

The presence of L. lemniscatus carcellesi, found living today only in Uruguay and Argentina, indicates a wider distribution for this taxon during the late Pleistocene.

In the dunes of "San Clemente del Tuyú", Province of Buenos Aires, fossils or subfossils are frequently found Conus:
