ME. S. HANLET ON THE LIITNEAN MS. OE THE ' MUSEUM ULRICiE.' 79 



Besides the published species, the following had been written, but omitted 

 in printing : — 



TuRRicuLA ALBA. T. alba recurvirostra, anfractibus margine crenu- 

 latis. 



Bon. 3. t. 84. Rumph. t. 30. f. K. Pet. Gaz. t. 56. f. 4. d'Arg. Conch, 

 t. 14. f. P. Gualt. Test. t. 57. f. D. 



Testa laevis. Anfractus circiter 15, margine subcrenati. Color albus, 

 saepius saturatior ad marginem anfractuum. Apertura ovata, rostro cana- 

 liculate, recurvo. Labium interius adnatum, dente unico obsoleto. 



This was evidently identical, from its synonymy, with the M. vertagus of 

 the * Systema.' 



TuRRicuLA SENTicosA. T. reflexo-cmarginata, costis reticulatis. 



d'Arg. Conch, t. 12. f. O. 



Testa gibba, costis saepius 12 perpendiculari-obliquis, intertextis striis 

 lamellosis transversis ad anastomosases muricatis, unde admodum scabra 

 evadit. Anfractus ventricosi, saepius x. Color griseus. Apertura ovata, 

 interne striata, emarginata, parum reflexa. 



Evidently this was identical with the M. senticosus of the * Systema.' 



M. OLEAGiNEUS. M. auguUs sulcis insequalibus, labio interiore rugoso, 

 costis altemis. 



Gualt. Test. t. 49. f. G. d'Arg. Conch, t. 13. f. M. 



Habitus et structura rubeculee, at octies major, nee vivide pictus, sed 

 colore testaceo fasciis fuscis longitudinalibus. Apertura intus saturate 

 crocea, rugis albis. 



Apparently this was the Triton pileare of authors, — not the Mediterranean 

 shell (T. corrugatus) termed M. pileare in the * Systema.' 



M. piLEUS Helveticus. M. angulis rotundatis, tuberculis conicis, 

 apertura utrinque canaliculata. 



d'Arg. Conch, t. 12. f. D. Rumph. t. 28. f. D. 



Testa ovata, admodum inaequalis, adspersa nodis conicis tuberculatis 

 inaequalibus. Costae latere antico membranaceae, primae 2 oppositae, reli- 

 quae alternae. Color flavus. Apertura hians, antice etpostice canaliculatae, 

 faux intus striata. Labium exterius dentatum, intus dilatato-membra- 

 naceum. 



This suits very fairly the Triton lampas of authors ; far better, indeed, 

 than does the M. Lampas of the * Museum Ulricae.' 



M. suBULATus. M. ecaudatus, pyramidahs. 



Testa subulata instar turris, anfractuum undecim, reticulata striis elevatis 

 decussantibus punctis contignationem eminentibus. Costae oppositae et 

 alternae. Color albus, maculis flavescentibus. Apertura ovata. Labium 

 exterius crassum, intus dentatum. Interius dentato-glabrum. 



Both Triton ! maculosus and Ranella candisaia approach the ideal por- 

 trait, yet neither of them precisely agrees. 



Under the name of Trochus turritus our author appears to have first 

 described his Murex radula. 



Trochus exumbilicatus, pyramidatus, anfractibus duplici serie muricatis. 

 Gualt. t. 58. f. F.
