3. Bulla pinguicula, Jeffreys. 



Bulla pinguicula, Gwyn Jeffreys, a MS. name published in List of Bay of Biscay " Travailleur " 

 Dredgings, Ann. and Mag. Nat. Hist., October 1880, ser. 5, vol. vi p. 318, 

 No. 140; also in Brit. Assoc. Report on the same, 1880, p. 10, No. 181. 



Station 75. July 2, 1873. Lat. 38° 38' N, long. 28° 28' 30" W. Off Fayal, Azores. 

 450 fathoms. Volcanic mud. 



Habitat. — Bay of Biscay. 



The solitary specimen of this species is very much broken, and the identification difficult. I was 

 indebted to Dr Gwyn Jeffreys for the suggestion that it belonged to his species ; his only hesitation 

 lay in the apparent absence of punctured spiral strias very characteristic of his species. A careful 

 examination, however, showed that these are really present, and set doubt at rest. The Challenger 

 specimens, however, are in too bad condition for description. I have no choice therefore but to 

 leave them undescribed under Gwyn Jeffreys' name.
