fusus. 75 



30. l^evigatus, f. 157, Sowerby. — Testa breviuscula, fulva, 

 castaneo strigata et maculata, acute subaltematim costata; 

 anfractibus supra medium angulatis, lougitudinaliter plicatis, 

 plicis rotundatis; apertura alba, sulcata, crenata, fauce fuscata, 

 canali brevi. — More angular and narrower than F. marmo- 

 ratus. 



30*. EuwcosTATus, f. 1 9, 1 64, Sowerby. — Testa F. mar- 

 morato similis sed costis spiralibus distantibus prominenti- 

 bus. — The spiral ribs are prominent and distant, and granu- 

 lated, and the general aspect differs from Philippics type of 

 marmoratus, f. 163. 



31. nodicinctus, f. 35*, A. Adams. — Testa F. Isevigato 

 similis, sed angusta ; recta, ad angulum acute carinata, an- 

 gulo nodoso articulate. — This has a row of tubercles articu- 

 lated with brown spots. 



32. BiANGTJLATCS,f.l59,Z)esAa?/e.s. — Testa marmorato similis 

 sed ultimo anfractu obtuse biangulato, fauce castaneo. — I do 

 not particularise the characters of this species, because, with 

 one exception, they are identical with those of F. rudicos- 

 tatus, the exception being the greater thickness and the 

 double angle (the roughest kind), and subject to the same 

 variations. Eeeve figures an example of the species as a 

 variety of F. polygonoides, as from Belcher's collection. 

 The specimen here figured is from Mr. Hanley's collection, 

 and may have been included with those which that gentle- 

 man had from Belcher's. 



33. subquadratus, f. 28, Sowerby. — Testa alba, angusta, 

 spiraliter lirata, anfractibus superioribus distanter costata, 

 inter costas purpureo-fuscata, inferioribus angulatis, ultimo 

 biangulato, ad angulum superiorem nodis prominentibus 

 acutis, apertura intus purpureo tincta, margine denticulato. 

 — A double row of tubercles forms a second angle at the 

 lower part of the last whorl. The shell is much narrower than 

 F. biangulatus. 



34. Pateli, f. 38, Bunker. — Testa alba, aureo inter liras et 

 costas strigata, spira breviuscula, lata, anfractibus 9 brevibus, 

 latis, vix prominentibus, acute tuberculato-costatis. — In some 

 respects resembling F. acuticostatus, but broader and less 

 sharply tubercled and ribbed. It has not the same prickly 

 appearance.
