Altitudinal range. The localities reported here range between “near sea level” and 2435 m.

Remarks. Bulimus leptochilus Pfeiffer, 1848  and Bulimus lindeni Reeve, 1848  were placed in the synonymy of this species by Pilsbry (1895: 40). The type locality for both is “La Baja, Province of Pamplona.” Richardson (1995: 202) was the first to group Bulimus plumbeus Pfeiffer, 1855  , hitherto considered a species of Thaumastus Albers, 1860  , together with Dryptus pardalis  . See also the remarks under D. moritzianus  , some records of which might be misidentified given that these species are closely related. There seem to be two distinct shapes of what is referred to as Dryptus pardalis  : (1) some are cigar-shaped, tapering about evenly at either side, with the central part having near-parallel outlines; and (2) some with the spire substantially less wide, and the body whorl wider, so the whole shell is more “bulimuliform” in appearance. In addition, there is substantial variation in sculpture, with some specimens being nearly smooth (even fresh ones), and others are very sculptured.

Two samples are tentatively referred to this species. One is from near Cúcuta ( UVZ 8101), corresponding to the second shape variation above. The other is a lot from Guajira, near Carraipía, ( USNMAbout USNM 543492). While these specimens look very different from other Dryptus  , they might be misshapen D. pardalis  . Specifically, they are too short, and have a very globose last whorl, which includes a much shorter aperture. One of the specimens has a strong parietal callus. Two reasons make it probable that they are D. pardalis  : (1) this species is known from the same locality (it is the only Dryptus  known from Guajira); (2) two other lots of D. pardalis  are known from Carraipía: USNMAbout USNM 543494 (2 specimens) and USNMAbout USNM 599500 (1 specimen). Furthermore, one could argue that the deformed specimens are shorter and globose due to climatic differences. Interestingly, the spire is not globose, it seems to be just the body whorl having this characteristic. However, the following arguments are against this classification: (1) two specimens are available and both are somewhat similarly misshapen; (2) these individuals are umbilicate (more so than any specimen of D. pardalis  ); (3) neither one has much of a columellar fold. As is the case for several other species of Dryptus  , D. pardalis  may be widely distributed in Venezuela; Tello (1975) listed four Venezuelan Estados (states) in the distribution of this species, including Táchira and Zulia (bordering with Colombia), with Cumaná (Sucre) being the easternmost record. However, these records are in need of critical review.
