72 ME. S. UANLEY ON THE LINNEAN MS. OF TUE 'MUSEUM ULBICiE.' 



The printed additions are considerable ; to wit, " costse vero striis trans- 

 versis", " anfractibus costis raueronatis", " denticulatum." 



B. Persicum. Lyra laeviuscula, labii margine crenulato. 



The erroneous citation of Grew (t. 9. f. 5, 6) in the ' Systema ' had been 

 adopted in the manuscript. 



B. PATULUM. Lyra muricata spinis obtusis. 



Neither the erroneous reference to Gualtieri, plate 51. f. A (which was 

 designed for Purpura h(Bmastoma), nor the ** color interne rufescens", is to 

 be found in the manuscript. 



B. SMARAGDULus. Lyra glaberrima, columella denticulata. 



Neither the erroneous reference to d'Argenville, nor the specific name 

 derived from his figure, is to be found in the MS. The proposed appel- 

 lation was L. vitrea. " Simillima Cassid. lapillo, sed glabra, et columella 

 crenata " is the unprinted remark. 



B. SPIRATUM. Morion umbilicatus, anfractibus distinctis canaliculo. 



The specified colouring was " alba, maculis longitudinalibus fuscis " : 

 " pone bifidum " followed " integrum." The intended name was M. ca- 

 naliculatus. 



B. GLABRATUM. Morion umbilico descendente flexuoso. 



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



" Testa oblonga, acuminata, obtusiuscula, glaberrima, anfractibus con- 

 fluentibus, Neritarum maximarum pondere. Color albo-flavescens, nitidus. 

 Apertura obliqua, profunde emarginata. Labium exterius integemmum. 

 Labium interius antice reflexum adnatum, dein solutum brevius flexuosum, 

 descendens ad basin. Sulcus profundus distinguit basin testae. Umbilicus 

 pone labium interius descendens ad basin sulco.'* 



B. viRGiNEUM. I can find no account of this shell in the written copy. 



B. UNDosuM. The nearest approach to this species seems the variety 

 B. of the Murex succinctus (the shell so named in the ' Mantissa'). 



M. Isevis, sulcis transversis laevibus, angulo marginali. 



d'Arg. Conch, t. 12. f. N. Bon. 3. f. 47. 



Testa ovata, absque tubercuhs, magnitudine nucis, exarata sulcis trans- 

 versis paUidis, eminentibus vero lineis luteis. Spira obtusa, anfractibus 

 rotundatis. Cauda teretiuscula. Apertura ovata, margine crasso, nee alia 

 costa laterali crassa. 



Var. B. Rugis s. angulis obliteratis 5 longitudinalibus. 



B. MACULATUM. Turricultt elongata, anfractibus laevibus iutegerrimis. 



The I. of Gualtieri, and the reference to d'Ai'genville,were printed emen- 

 dations. 



B. CRENU LATUM. Turric. elongata, anfractibus margine crenatis. 



The reference to Gualtieri was an emendation. 



B. STRIGI LATUM. Turric. elongata, oblique striata. 



B. DUPLICATUM. Turric. elongata emarginata, anfractibus bipartitis 

 striatis.
