which it may be known by the contraction of the aperture below 

 and the remarkable frill-like epidermis round the sutures. The 

 apex is papillose in all the specimens I have met with. Length 

 9 lines. 



51. COLUMBELLA (MiTRELLa) LINCOLNENSIS. 



Columhella lincolnensis, Reeve, Conch. Icon, pi. 29. f. 184 a, h. 



A pretty fusiform species, not unlike C. corniculata, Lara., from 

 the Adriatic. Rare, under stones in Port Jackson. The type spe- 

 cimens, as the name imports, are from Port Lincoln in South Au- 

 stralia. Length 6 lines. 



52. *COLUMBELLA (MtTRELLA) ALBOMACULATA. 



Columbella albomaculata, Angas, P. Z. S. 1867, p. 111. 



A solid fusiform species, mottled with chestnut, and ornamented 

 with clusters of white spots immediately below the sutures. Under 

 stones in Port Jackson. Length 6 lines. 



53. Columbella (Mitrella) pulla. 



Columhella pulla, Gaskoin, P. Z. S. 1851, p. 6; Reeve, Conch. 

 Icon. pi. 19. f. 106. 



A dark-brown species without markings, found under stones in 

 Port Jackson. (Strange, in Cum. Coll.) Length 7 lines. 



54. Columbella (Amycla) dermestoides. 



Columhella dermestoides, Kiener. 



C. tessellata, MS. Mus. Cuming ; Sow. Thesaurus, pi. 39. f. 123. 



This very beautifully tessellated little species is certainly conspe- 

 cific with the C. dermestoides of Kiener, which species, however, is 

 recorded as coming from the West Indies. I have one or two speci- 

 mens from South Australia, where, as well as in Port Jackson, it is 

 very rare. My specimens were dredged in 5 fathoms of water at 

 Watson's Bay. Length 5 lines. 



55. Columbella (Anachis) lentiginosa. 



Columbella lentiginosa, Hinds, Moll. Voy. Sulphur. 



A very small longitudinally ribbed species, of an olive-brown 

 colour, having a slight tendency to a pale band near the sutures. 

 Under stones in Port Jackson, also jNIoreton Bay. Length 2 lines. 



56. *^SOPUS FILOSUS. 



Msopiis flosus, Angas, P. Z. S. 1867, p. 111. 



An elegant fusiform shell, belonging to the genus uEsopus of Gould, 

 with the columella arcuate and smooth, and the whorls closely trans- 

 versely lirate. The colour is either brown or white. Dredged in 

 Port Jackson. Length 6 lines.
