This appears to be one of several species confounded under 

 the Linnean T. doliarium. Deshayes has indicated it as a dis- 

 tinct species, but has not described it. The coloring is like T. 

 doliarium, but the form and cincture is more like T. ciUaceiim. 

 The aperture and lip is like T. pileare^ and it may be regarded 

 as intermediate between the two latter species. 



Triton mdndum. Testa parva, solida, oblongo-rhomhoidea, 

 straminea, epidermide tenui, sparsim hirsute induta: spira conica, 

 anfr. 4, convexiusculis, ultimo gibboso, tri-nodoso, in rostrum 

 rectiusculurn attenuate, costulis tribuset liris intermedianis cincto 

 et filis continuis longitudinalibus decussato : apertura angusta, 

 ovalis, ^ testse adequans ; labro crasso, tuberculis geminatis 7 

 crenato ; columella arcuata, postice dentifera ; fauce albo. 

 Long. -^-; lat, f poll. Hah. Tutuilla, Samoa Islands. 



This might be regarded as the young of T. nodosum ; but 

 besides bearing all the marks of maturity, it is more slender, the 

 longitudinal lines are stronger, and the lip is white. 



Phos varicosus. Testa elongata, lanceolata, fulvida, rubi- 

 ginoso-cinctaj costis lamellosis ad 16 clathrata, quorum circiter 3 

 in singulis anfractibus, variciformibus, pallidioribus, interspatiis 

 duplo latioribus, concavis et lineis increment! striatis, omnibus 

 filis volventibus retrorsum acclinatis decussatis : spira turrita, 

 anfr. 9-10 superne turgidis: apertura angusta, lunata, postice 

 rotundata ^ long, testa3 adequans; labro simplici, intus sulcato, 

 rosaceo ; columella 4 plicata ; canali siphonali brevi. Long. 1^, 

 lat. ^^ poll. Hah. Philippine Islands. 



This curious shell is somewhat anomalous, having the varicose 

 spire of a Triton, but the unequivocal aperture of Phos. It 

 may be compared with P. retecosus, Hinds, having the more 

 slender form and finer reticulation, but with the peculiar varicose 

 lip, and nearly the same size and color. It is perhaps still more 

 like P. senticosus., but it is much less asperous, and peculiarly 

 inflated near the suture. 



MuREX (Trophon) fruticosus. Testa parva, tenuis, subrhom- 

 boidea, straminea : spira anfr. 5-6 angulatis, superne concavo- 

 declivibus, serie mediani spinarum armatis, spinis ad 6 tubulosis, 

 subramosis, recurvo-adscendentibus ; anfr. ultimo series tres 

 spinarum lamellis longitudinalibus conjunctarum gerente : apcr-
