72 MR. S. UANLEY ON TUE LINNEAN MS. OF THE 'MUSEUM ULEIC^.' 



Tlie printed additions arc considerable ; to wit, " costae vero striis trans- 

 versis", " aufractibus costis mucronatis", " denticulatum." 



B. Persicum. Lyra Iseviuscula, 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 rauricata spinis obtusis. 



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

 designed for Purpura heemastoma), 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 s])ecitic name 

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

 lation was L. vitreu. " Siniilhma Cassid. lapillo, sed glabra, et columella 

 crenata " is the unprinted remark. 



B. SPIRATUM. Morion umbilicatus, aufractibus distinctis canaliculo. 



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

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

 naliculatus. 



B. GLABRATUM. Moriou umbilico descendente flexuoso. 



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

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

 Labium interius antice reflexum adnatum, deiu 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. laevis, sulcis transversis laevibus, angulo marginali. 



d'Arg. Couch, t. 12. f. N. Bon. 3. f. 4?.

 costa laterali crassa. 



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

The L of Gualtieri, and the reference to d'Argenville, were printed emen- 

 dations.

The reference to Gualtieri was an emendation.
