E. A. Smith (Jcscril)cd from Kcrguclcn. It is a much more solid shell 

 than T. geTcrsiatii/s, ;ind narrower, with fewer and less regular spirals; 

 the suture is not so deeply impressed ; the lip is thicker, and the 

 mouth less obli(iue, whilst the canal is much shorter. Specimens 

 were dredged by the ' Challenger ' Expedition in three stations off 

 Royal Sound, Kerguelen, from volcanic mud, in 25 to 60 fathoms 

 (Watson). 



T. buccineus Clray. — One specimen, in perfect condition, which 

 exactly matches the excellent figure copied by Tryon. No description 

 or locality is given, but the shell is allied to T. pltimbeus A. Gd., and 

 is a light chocolate-brown colour, deeper within the aperture. 



T. cretaceus Rv. — One rather large example, in the usual worn 

 condition. Recorded from the coast of Chili. 



T. geversianus Pall. (PI. I., fig. 10, PI. II.). — Six examples of 

 this beautiful species. One is a particularly handsome specimen, 

 snowy white, with well developed broad frill-like lamellns, and in 

 excellent condition. It indeed so far surpasses in size and beauty 

 the types figured in Reeve's "Conchologia Iconica'' and elsewhere, 

 that it has been thought worth while to figure two aspects of this 

 shell. This particular specimen is in J. C. Melvill's collection. Two 

 others almost equal it in size, but are not so perfect in condition. 

 The rest are juvenile. With the collection there is a string of egg- 

 capsules of this species. They are of a yellowish colour, spoon- 

 shaped, closely set together, and in size average 2ox 12 mm. In 

 each capsule there are a quantity of embryos, measuring 25 mm. in 

 length; the contents of two capsules were carefully counted and 

 found to contain, respectively, 74 and 112 baby shells. One of these 

 is figured (PI. I., fig. 10). The species is extremely variable, and 

 occurs from Magellan's Strait to Chili. The synonymy is exten- 

 sive and includes, amongst others, Buccinum fimbriatuin Martyn, 

 Mutex tnogellanicus Gm., M. folia tus Schum., AT. peruvianus Enc. 

 Meth., M. lamcllosHs Dillw., and AI. patagonicus D'Orb. 



T. laciniatus Martyn. — One, not quite adult, but otherwise very 

 perfect. The absence of the characteristic latticed sculpture in the 

 interstices between the lamelL-e readily distinguish this from T. gever- 

 sianus. It is recorded from Magellan's Strait by Tryon, and from 

 the Chonos Archipelago by Reeve. Tryon unites this species and 

 7! antarcticus Phil., and expresses some doubt as to whether these 

 South American forms really belong to the genus Trophon. 



T. muriciformis King. — Five very beautiful and perfect ex- 

 amples. An ovately fusiform, cinereous species, with tumid, cancel- 

 lated whorls ; dark chestnut aperture, and crenulated lip, which 

 amply differentiates it from T. geversia?n<s, with which Tryon is
