THE VOYAGE OF H.M.S. CHALLENGER. 
1850. Cuvieria urceolaris, M0rch, Catalogus conch yliorum quae reliquit C. P. Kjerulf, 
p. 32. 
1879. Triptera columella (sic), Pfeffer, Uebersicht der auf S.M. Schiff “ Gazelle ” und von Dr. 
Jagor gesammelten Pteropoden, Monatsber. d. k. preuss. 
Akad. d. Wiss. Berlin, 1879, p. 243, fig. 18. 
1879. Triptera cancellata, Pfeffer, Ibid., p. 243, fig. 19. 
For description and figures I refer to Souleyet, Voyage de la Bonite, Zoologie, t. ii. 
p. 205, pi. xii. The best figure of the complete shell is to be found in the Spolia 
atlantica of Boas, pi. iii. fig. 39. 
Habitat. — Atlantic Ocean ; from 43° 23' N. (Boas) to 40° S., both towards the New 
and Old Worlds. According to Souleyet, this species has been found towards Cape Horn, 
but this appears to me to require confirmation. The locality Spitzbergen, noted in the 
British Museum, is certainly erroneous. 
Indian Ocean; from the Gulf of Bengal (British Museum) to 35° 30' S., from Africa 
(Zanzibar, the Cape, &c.) to Australia. 
Pacific Ocean ; western portion, China Sea (Boas), Malay Archipelago, east coast 
of Australia (Pfeffer and Angas) ; eastern portion, from 23° N. to 42° S. (Knocker).
