64 TROPHON. 



purpurascens, costis crassis rotundis, liris validis subdistanti- 

 bus decussatis sculpta; spira breviuscula, anfractibus paucis, 

 angulatis; apertura subquadrata, intus purpurea, labio 

 externo crasso, extus varicoso. — Eatlier more murex-like 

 than the preceding and others of similar form. 



21. carduds, f. 5, Broderip. — Testa oblique quadrata, 

 albida, medio pallide fuseo unifasciata ; spira acuminata, 

 anfractibus declivibus, subtus angulata, ultimo longitu- 

 dinaliter costato, costis tuberculatis, canali brevi, extus 

 anguste laminato, umbilicato ; apertura subtrigona, margine 

 spinoso. — Of a singular lozenge form and sharply angular 

 above the middle of the whorls. 



22. muricatus (as Fusus, pi. iv. f. 27), Montfort. — Testa 

 fusiformis alba vel fusca; spira acuminata, anfractibus 

 rotundis, longitudinaliter plicatis, spiraliter rugos'o-liratis, 

 liris super plicas submuricatis ; apertura claviformi, labio 

 externo subexpanso crenato, canali angusto recto. — Having 

 inadvertently figured the Mediterranean variety of this 

 among the Fusi, and also omitted the British variety in both 

 Monographs, I am placed in a difficulty, and can only repeat 

 the name in this genus or subgenus, to which, as at present 

 constituted, it does not really belong : the British variety is 

 more delicate in sculpture and colouring. 



23. Barvicensis, f. 12, 52, Johnson. — Testa albida, quam 

 T. muricatus magis angulata, latior, distanter muricato- 

 costata, subdistanter lirata ad angulum anfractuum spinosa, 

 canali brevi, truncate — A broader and shorter shell than 

 T. muricatus, cancellated with distant laminated ribs and 

 spiral ridges. The canal is short, thick, and truncated. 



24. fimbriatulus, f. 49, 50, Adams. — Testa pallide rosa- 

 cea, breviter fusiformis, laminatim costata, liris crebris, ad 

 costas crispatis cincta, anfractibus angulatis ; apertura pyri- 

 formi, labio externo lato expanso, fimbriato, canali subclauso. 

 — It is not without hesitation that on account of its 

 laminated structure I admit this species in the present 

 genus, its canal being partly plated over, as in Murex. 



Species 25 omitted. 



26. orpheus, f. 28, Couthoy. — Testa subovata, brevis, 

 albida, regulariter cancellata; spira producta, anfractibus
