Var. crassilirata, n. var. 



This is slightly larger, 45 mm. long and 1'7 mm. broad, 

 and more solid, with the same number of spirals, but these 

 are much stoixter, the infrasutural cord being specially round 

 and conspicuous. 



Dredged in 55 fathoms off Cape Borda, 1 very good. 



Mitromorpha pallidula, Hedley. 



Mitromorpha pallidula, Hedley, Proc. Linn. Soc, New South 

 AVales, 1905, vol. xxx., part 4, p. 534, pi. xxsii., fig. 26, "Manly 

 Beach, near Sydney," also "24 fathoms off Derwent River, Tas- 

 mania" : Gatliif. Proc. Roy. Soc, Victoria, 1907, vol. sx. (N.S.), 

 part i., p. 32, "Port Albert." 



Dredged in 35 fathoms off St. Francis Island, 1 alive; 

 in 62 fathoms off Cape Borda, 1 moderate ; in 90 fathoms off 

 Cape Jaffa, 2 poor ; in 130 fathoms off Cape Jaffa, 8 good ; 

 in no fathoms off Beachport, 6 good. 



Natica sticta, n. sp. PI. xxix., tigs. 4, 5, and 6. 



Shell solid, ovately-globose, of 3h whorls. Spire scarcely 

 raised, whorls flatly convex. Suture distinct, linear. Aper- 

 ture semi-circular ; outer lip thin, simple. Inner lip distinct, 

 raised into a callous pad, which, with that of the straight 

 columella, almost completely fills the large umbilicus. In, 

 young shells the umbilicus is wide, open to the apex, and 

 with a spiral funicle winding up to the middle of the colurn- 

 ella. Surface shining and smooth, but for sublenticular ac- 

 cremental scratch-lines, most marked at the border of the 

 umbilicus. There are three spiral rows of brown marks, axi- 

 ally elongate, and somewhat zigzag. 



Di7n. — Length, 8'5 mm.; breadth, 7 mm.; height, 5'25 

 mm. 



Locality. — TyjDe from 130 fathoms Cape Jaffa, with 

 many others quite fresh. Dredged also in 16 fathoms out- 

 side Backstairs Passage, 3 good; in 17 fathoms Gulf St. Vin- 

 cent, 5 ; in 40 fathoms off Beachport, 26 good ; in 45 fathoms 

 east of North Neptunes, 4 ; in 55 fathoms off Cape Borda, 

 15 dead, also in 62 fathoms, 29 minute; in 110 fathoms off 

 Beachport, 60 ; and in 150 fathoms, 1 fresh. 



As no individual was taken alive to provide an oper- 

 culum, the genus is not certain ; but I think it will prove to 

 be a Nafica with a shelly operculum. Some shells have an 

 additional ornament in a dull-brown infrasutural continuous 

 band.
