Dear Harry,
Wow, you got to the heart of that one! It is interesting how the small
type rn (RN) looks like m (M). I was at first confused by your posting
because my eyes could not discern the difference, hence the typo in the
Zoological Record. I suppose that rr (RR) is a similar mistake. Well done
Harry!
I did find a record in Poggendorff of a Dr. Johannes Gundlach, Professor of
Mathematics and Physics at the University of Marburg, who died in 1819.
Perhaps a predecessor?

Dear Scott,
The species in question is assigned to Tomelasmus (with an M; type:
Cylindrella
torquata Morelet, 1849), a generic unit erected by Pilsbry and Vanatta in
1898
("Proc. Acad. Nat. Sci. Phil. p. 271, 276") according to Jaume, M. L. and
A. de
la Torre, 1976. Los Urocoptidae de Cuba (Mollusca - Pulmonata) Ciencias
Biologicas Serie 4 53: 1-122. Feb.
In 1903 (Manual of Conchology 15: 235), Pilsbry reported that the
Zoological
Record for 1898 misspelled this name "Tornelasmus." (with an RN). The
complete
citation of the paper in which this taxon (as a "section" of Urocoptis) was
proposed is:
Pilsbry, H. P. and E. G. Vanatta, 1898. Materials toward a natural
classification of the cylidrelloid snails. Proceedings of the Academy of
Natural Sciences of Philadelphia 50: 254-286, pls. 17-18. July 12.
Cylindrella irrorata Gundlach, 1856 from "San Diego de los Banos (Cuba) on
stones" was placed in Tomelasmus in the original (1898) paper. Pfeiffer's
use
of this binomen post-dates that of his countryman.
My specimen is from "Magote Herrera, San Diego de los Banos, Pinar del Rio,
Cuba" according to Walter F. Webb's (circa 1950) label.
I first thought the name you posed was a misspelling of "Torrelasmus" (two
R's;
after Dr. de la Torre like several other Cuban taxa), but that name doesn't
exist either.
So you've got three misspellings (my Torrelasmus, your Torelasmus, and the
Zoo.
Record's Tornelasmus) and only one correct one (Tomelasmus). The latter
refers
to the "cut plate" or serrated sub-basal lamella of the type species and
certain relatives.
Happy Holidays,
Harry
