In the British Museum are exhibited a series of three, marked 

 "types, scalarinus A. Adams, P.Z.S., 1863, p. 508, = Triton(Cumia) 

 speciosa Angas, P.Z.S., 1871, p. 13, PL i., f. 7. Port Jackson." 

 Beside these, another series of three, the types of speciosa, are 

 marked " = scalarinus A. Adams." 



It was characteristic that A. Adams should fail to observe that 

 the Triton speciosus of his literary partner Angas, was his own 

 Murex scalarinus. Having left his species, in the wrong genus, 

 unfigured, unlocalised, known and knowable only to those who 

 saw the type, Arthur Adams fortunately crowned his work by the 

 adoption of a preoccupied name. Hence we are relieved from the 

 necessity of following the British Museum procedure, and abolish- 

 ing the well-worn name of speciosus. 



Under the genus Craspedotriton Dall, the British Museum in- 

 cludes this species in association with convolutus Brod., and scala- 

 riformis Brod. While agreeing with the reference to Craspedo- 

 triton, 1 would suggest that the information on the apex, radula, 

 and operculum of speciosus, supplied by Kesteven, supports a 

 transference of Dall's genus from the neighbourhood of Triton to 

 that of Trophon. Petterd's T. eburnea represents a comparatively 

 smooth southern form of C. speciosus.

Deshayes has commented on the loss of the identity of this 

 species, which, after a disappearance of ninety years, it is my good
