Helix brachysoma d'Orbigny, 1835 Figs 52C-D

Helix brachysoma d’Orbigny 1835: 18.

Bulimus brachysoma d’Orbigny 1837 [1834-1847]: 309, pl. 39 figs 9-10 [7 Aug. 1837; text 6 May 1838].

Type locality.

"provincia Santa Cruz de la Sierra (republica Boliviana)"; see Breure 1973: 115.

Dimensions.

"Longit. 40 millim., latit. 19 millim.".

Remarks.

In the NHMUK copy of the ”Voyage...”, there is a note in pencil in the margin of p. 309, which states "No examples of this sp. could be traced in d’O. colln. in Sept. 1958. S.P. Dance". Also, in Gray (1854) there is no ”B.M.” following the name, so it may safely assumed that type material of this taxon never came to London. As this species has not been traced in the Paris museum ( Breure 1975b), the type material must be considered lost. The original figures of d’Orbigny are here reproduced.

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) brachysoma ( d’Orbigny 1835).
