REMARKS

See above the discussion under Weltnerium bouvieri .

OTHER SAMPLES FROM THE ATLANTIC OCEAN Gruvel (1902a: 53, pl. 2, fig. 3a; 1902d: 523) cited the occurrence from the Atlantic ( Talisman Expedition, 1883 , drag. 138, 46°9’N, 9°16’W, 4787 m, MNHN Ci 368) of Scalpellum gigas Hoek, 1883 (now in Trianguloscalpellum ), which was described from the mid-Pacific region (Challenger Expedition, stn 246, 36°10’N, 178°0’E, 3740 m). The single specimen ( Fig. 29 ) carried on some males, which were described in the same study (1902: 126, pl. 3, figs 22-26). Due the wide discrepancy between the distribution range of S. gigas and the Gruvel’s record from Azores region, Young (1998a) considered this citation a mistake and considered it as probably T. ovale ( Hoek, 1883) , a species similar to T. gigas with an Atlantic distribution.

The examination of the specimen identified by Gruvel confirms that this is actually T. ovale ( Fig. 29 ). The general form of the capitulum and the large contact area between the carino-latera agree with the diagnosis of T. ovale . Furthermore, the record of T. gigas from Bay of Biscay of Foster & Buckeridge (1995) is indeed T. ovale . The three specimens from this sample agree with the T. ovale diagnosis.
