STRUTIIIOLARIA, 



Genus STEUTIIIOLAFJA, Lamarck. 



Testa oMoni/o-ovalis, spird exsertd, anfractibus stiperni jjIhs 

 minus nodoso-angulatis, columella valde callosd, c.vca- 

 va/d, subtortuosd, basi obtuse truncatd, lahro fhrum- 

 (pie incrassato, pecuUariter sinuato. 

 Shell oblong-oval, spire exserted, whorls more or less uo- 

 dosely angled round the upper part, columella very 

 callous, excavated, slightly twisted, obtusely trun- 

 cated at the base, lip generally thickened, pcculinrly 

 siuuated. 

 The genus Slruihiolarla, which is intimately allied with 

 Strombus and Rostellaria, consists of four species only. 

 They are limited to particular localities, and have been 

 long known. Three inhabiting New Zealand, were named 

 and figured by Martyn in 1784, and the fourth, from New 

 Holland, was described by Lamarck. Owing to the diffi- 

 culty of getting access to the work of the English con- 

 chologist, a great deal of confusion has arisen in the no- 

 menclature of this genus. Chemnitz, however, hr.d a 

 copy of the work, and it is to be regretted that Martyn's 

 specific names were not followed in the Conchylien 

 Cabinet. 



Species 1. (Mus. Cuming.) 



Strutiiiol.vria Adstralis. Struth. testa ovatd, wiitri- 

 cosd, spird iurritd, suturis interdum simplicibus, hi- 

 lerdum caiialiculatis aid plano-excavatis, anfractibus 

 Iransversim striatis H swperficialiter sulcatis, superne 

 leviter declivibus, ad anguluni minute nodulatis, nodulii 

 interdum evanidis ; albidd, fuscesceuie tinctd et pallide 

 strigatd, colmnelld et labri limbo attrautiis. 



The Australian Struthiolaria. Shell ovate, ventri- 

 cose, spire turretod, sutures sometimes simple, some- 

 times channelled or flatly excavated, whorls trans- 

 versely striated and superfcially ■ grooved, gently 

 slanting round the upper part, minutely noduled at 

 the angle, nodules sometimes obsolete ; whitish, 

 stained and faintly streaked with light brown, colu- 

 mella and edge of the lip tinged with orange.

 Struthiolaria cremdata, Lamarck. 

 Struthiolaria iuermis, Sovverby. 

 Struthiolaria vermis, Deshayes. 



Ilab. Australia.

This species, first described by Gmelin, and the only I'ue 

 from Australia, is not the Bucciiimn vermis of JIartyn, a^ 

 supposed by M. Deshayes. It is uniformly of smaller 

 size, the nodules are closer together, and in specimens at 

 all larger than that in the accompanying plate, the nodules 

 are generally obsolete. The shell figured by Martyn is 

 much larger than the largest individual known of the 

 species under consideration ; it is, witliout doubt, an im- 

 mature specimen of Mr. Sowerby's Struthiolaria (jiyus. 

 \i\ S. cremdata the sutures of the whorls are sometimes 

 broadly channelled throughout. 



Species 2. (Mus. Cuming.) 

 STRUTIIIOLARIA SCUTULATA. Strutk. lestd ovato-comcd, 

 crassd, ponderosd, spird exsertd, suturis valde callosis, 

 anfractibus superne declivibus, deinde obtuse bicariuatis, 

 (ipicem versus minute nodatis, columella callosd, aper- 

 turd parvd, labro simplici ; Jlavido-spadiced, lineis 

 tenuibus fuscis longitudinaliler Jlexuoso-striyaid, cal- 

 lositate suturali albd. 

 The COBWEB-MARKED STRUTHIOLARIA. Shell ovately 

 conical, thick, ponderous, spire exserted, sutures very 

 callous, whorls slanting round the upper part, tlieu 

 obscm-ely two-keeled, minutely nodided towards tin- 

 apex, columella callous, aperture small, lip simple . 

 yellowish fawn-colour, longitudinally flexuously 

 streaked with fine brown lines, sutural callosity whiti'. 

 Buccinum scutulatum, Martyn, Universal Conchologist, 

 vol. ii. pi. 55. 



Slrutliiolaria scutulata, Deshayes. 

 Struthiolaria oblita, Sowerby. 

 llah. New Zealand. 



Distinguished by its solid enamelled growth, and simjjle 

 lip, and by the sutures of the spire being filled with cal- 

 losity. The painting consists of numerous flexuous hair- 

 lines. Chemnitz's figure of this species appears to be a 

 co]5y of that of Martyn. 



Species 3. (Mus. Cuming.) 



Struthiolaria papulosa. Struth. testa iiyramidali- 



ovatd, spird subturritd, anfractibus uHdi(pie tenui et 



creherrime sulcatis et striatis, superne concavo-decU- 



vibus, acute angulutis, ad an-juUim muricato-Hudatis, 



1851.
