tricosd, anfractibus rotundatis, longitudinaliter costatis, 
liris transversis angustis binis peculiariter clathratis ; 
alba, epidermide setosd cristatd indutéa.

Triton Oregonense, Say, Aun. Lyc. Nat. Hist. v. iv. p. 165. 
pl. 11. f. 2. 
Hab. North America. 
Distinguished from the following well-known species by 
the latticed sculpture being of a much larger and wider 
character, with the transverse ridges ranging in pairs. 
Species 62. (Mus. Cuming.) 
Pusus canceLiatus. Fus. testé subfusiformi, ovata, tent, 
ventricosd, anfractibus costis parvis longitudinalibus et 
transversis undique cancellatis, costis labrum versus 
evanidis ; columelld callositate superné munitd ; albd, 
epidermide fibrosd induta. 
THE CANCELLATED Fusus. Shell somewhat fusiformly 
ovate, thin, ventricose, whorls cancellated through- 
out with small longitudinal and transverse ridges, 
ribs becoming fainter towards the lip; columella 
furnished at the upper part with a callosity ; white, 
covered with a fibrous epidermis. 
Triton cancellatum, Lamarck, Anim. sans vert. (Deshayes’ 
edit.) vol. ix. p. 638. 
Hab. Unalaska, Kamtschatka. 
Although this shell is uniformly of larger size than the 
preceding, the cancellated sculpture is of a smaller cha- 
racter and the epidermis less bristly or tufted. 
Species 63. (Mus. Metcalfe.) 
Fusus rornicatus. us. testd ovatd, ventricosissimd, 
anfractibus superné peculiariter declivibus, deinde angu- 
latis, ad angulum carinatis, carind labrum versus in 
nodis tumidis mutatd, colunelld basi contortd ; fusco- 
rufescente. 
THE VAULTED Fusus. Shell ovate, extremely ventricose, 
whorls peculiarly slanting round the upper part, then 
angulated, keeled at the angle, keel changed towards 
the hp into swollen nodules, columella twisted at the 
base ; reddish-brown.

Hab. 
Of a more smooth horny character than £. despectus, 
whilst the whorls slant round the upper part in a peculiar 
manner, and the angular keel becomes changed towards 
the lip, into one or two large swollen nodules. 
Species 64. (Mus. Metcalfe.) 
Fusus pastinaca. us. testd fusiformi, tenui, tumidius- 
culd, anfractibus superné leviter concavis, deinde obsolete 
nodosis, undique spiraliter sulcatis, sulcis subirregula- 
riter undulatis, binis ; alba, epidermide tenui lutescente 
indutd. 
THE PARSNIP Fusus. Shell fusiform, thin, rather swollen, 
whorls slightly concave round the upper part, then 
obsoletely nodose, spirally grooved throughout, 
grooves somewhat irregularly waved, two and two; 
white, covered with a thin yellowish epidermis. 
Hab. Australia. 
A shell of very delicate structure quite unlike any former 
species.
