OTHER SAMPLES

Gruvel cited Verruca stroemia (Müller, 1776) in four of his studies, but only in three did he list the material studied. The one from 1905 was the revision of the cirripeds, in which he cited the general distribution observed by Darwin (1854): coasts of France and England, Mediterranean, Red Sea. Otherwise, he cited the following samples: – Gruvel (1902: 91): Expédition du Talisman, Azores , drag. 128, 38°7’N, 29°32’W, 960- 998 m, on gorgonians;

– Gruvel (1903: 100): Mission de la Manche (1892), “Rey Riawick” (Reykjavik, Iceland on the original label) and “Patrix Fjord” (probably Patreksfjördur, Iceland) and Mission Pouchet (1896), “Vadso, Finmark” (probably VadsØ, Norway);

– Gruvel (1920: 50): Campagnes Scientifiques de S. A. S. le Prince de Monaco, stn 1043, 59°03’N, 1°47’45”W, 88 m and stn 2354, no coordinates, 2600 m on living Neptunea antiqua (Linnaeus, 1758) , Sipho gracilis (da Costa, 1778), Natica catena da Costa, 1778. This last station is probably a label error because it does not appear at the “Tableaux des espèces recueillies aux différentes stations” at the end of his study.

In the collection of MNHN, there are four samples identified by Gruvel as Verruca stroemia , which were reexamined:

– Expédition du Talisman, Azores , drag. 128, 38°7’N, 29°32’W, 998- 960 m, 1883, five empty shells rc 1.7 to 2.7 mm (MNHN Ci 83), represents the information of Gruvel (1902). These specimens are represented only by shells and can be identified as Verruca spengleri Darwin, 1854 , because their shells have no longitudinal ridges. The suture between the rostrum and carina is also very elaborate and large as figured by Young (1998a). Otherwise, the locality is well within the region of occurrence of V. spengleri and not V. stroemia . Probably, these specimens were not living at the depth recorded, but were transported from shallower waters. The known depth range of V. spengleri is shallower than 100 m;

– Reykjavik, Mission de la Manche, 6 spec. and fragments rc 2.9 to 3.8 mm ( MNHN Ci 84). This sample represents V. stroemia as published by Gruvel (1903) ;

– Patrixfyord [sic], Mission de la Manche, 2 spec. and fragments rc 2.9 to 3.9 mm ( MNHN Ci 82). This sample represents V. stroemia as published by Gruvel (1903) ;

– No locality, 1 spec. and fragments rc 3.4 mm (MNHN Ci 86). This sample contains specimens of V. spengleri instead of V. stroemia , but no data on locality are known.
