128 DR JAMES COSMO MELVILL AND ME ROBERT STANDEN ON THE 



Hob. Trawl, Burdwood Bank, south of the Falkland Islands, 56 fathoms. 

 Station 346. 



A curious species, and one of which we are not quite sure of the proper position 

 generically. It seems, however, to agree with Turbonilla in more than one feature. 

 It is very delicate, resembling a terrestrial Opeas or others of the family Stenogyridse, 

 both in substance and form. Several examples occurred, the live specimens retaining 

 a subpellucid appearance and dull straw-colour. (^eco^^V, strange of form.)

Very young specimens are probably referable to this species. Another, judging 

 alone from the plate (STREBEL, Zool. Jahrbuch, Band xxi., Taf. vii. fig. 56, 1904), 

 might belong to T. Paessleri, Streb. We cannot, however, help feeling that too many 

 species have been created in such a variable assemblage as this section of the genus 

 Trophon presents.

 South Orkneys, at 9-10 fathoms. Station 325. 



Three or four more examples occurred, but the species is evidently rare. For the 

 nomenclature of this species, and its authorship, see remarks under Cerithiopsis 

 malvinarum.

 young condition, and found in Sponge. Station 346.
