340 " THETIS " SCIENTIFIC RESULTS. 



but from which it is easily distinguished by the slender form, 

 small size and absence of lirse within tj^ lip. Tryon* follows 

 Schmeltzf in i^egarding Triton fraterculus, Dunker,| as a synonym 

 of T. bassi, Angas, but it seems to me that the description of T. 

 granulatum, Dunker, suits T. bassi better than does that of T. 

 fraterculus. A recent addition to the Lotoriidse of New South 

 Wales is L. nodocostata, Tate & May, which I dredged in 100 

 fathoms sixteen miles east of Wollongong. 



A single living specimen was dredged in 22 fathoms off the 

 Manning River. 



LOTORIUM PARKINSONIANUM, Perry, emend, sp.

A few apices of this species were procured in 41-50 fathoms oft 

 Cape Three Points, and in 63-75 fathoms off Port Kembla. 



Family CASSIDID^. 



CASSIDEA, Bruguiere. 



The generic name Cassidea, proposed by Bruguiere, § and sup- 

 ported by Perry and Swainson, has been generally overlooked, 

 but it is certainly entitled to precedence over Semicassis, which 

 if cited as of Klein must be rejected as prelinnean, but if as of 

 Morch, is more than half a century younger. 



CASSIDEA TURGID A, Eeeve, sp. 



Cassis turgida, Reeve, Conch. Icon., v., 1848, Cassis, pi. x., f. 25.

Stations 48, 56. 



The "Thetis" took a large shell 100 mm. in length, thin, with 

 rounded whorls and brown zigzag markings on a white ground. 

 It is with diffidence that I record it under the above name, as it 

 lacks the denticules on the lip and exceeds Reeve's figure in size.
