88 MR. S. HANLEY ON THE LINNEAN MS. IN THE ' MUSEUM ULEICiE.' 



P. TUBERCULATA. P. dcntata conica tuberculata, postice sima. 



Sima was the earlier name in the MS., but was erased by Linnaeus. 



P. LUTE A. P. integerrima striata, vertice mucronato inflexo. 



P. UNGUIS. P. ovali-oblonga, apice emarginata, muerone dorsali 

 carinato. 



Unguiformis was the intended appellation. 



P. TESTUDINARIA. P. ovata glabcrrima integerrima. 



P. RUSTICA. P. integra, striis 60 obtusiusculis. 



P. FUSCA. P. ovata integerrima, striis elevatis, vertice obtuso. 



The intended name was cinereo-nigricans. 



P. CRUCIATA. P. ovalis convexa integerrima, cruce picta. 



P. RETICULATA. P. conica corapressa, superficie reticulata. 



The suggestion I have elsewhere made that this uncertain shell might 

 prove the European Pedicularia, induces me to remark that, although P. 

 Sicula has been supposed to be a comparatively modern discovery, Favanne 

 had long ago delineated it in the fourth plate (f. H. 1.) of his enlarged 

 edition of d'Argenville. 



P. NiMBOSA. P. conica ovalis, costis confei-tis, vertice perforate. 



The discrepancy between the heading borrowed from the ' Systema', and 

 the after details, is removed by the substitution of the original one. The 

 shell was termed perforata (not nimbosa), and was wrongly identified by 

 Linnaeus with the striated brown Fissurella of the * Systema'. 



In addition to the printed species, the two following were present in the 

 manuscript copy. 



P. SOLARIS. P. ovata integerrima, striis subnodosis, vertice acutiusculo. 



Testa ovata, diaphana, magnitudine extimi articuli digiti, margine inte- 

 gerrimo, Isevis, striis subtilissimis insequalibus numerosissimis, fasciis lon- 

 gitudinalibus rubris albo passim maculatis. Mucro acutiusculus obhquus 

 albidus. 



This was placed in the section having a simple margin. 



P. PERFOLIATA. P. couica, rccliuata, perfoliata. 



Testa magnitudine coryli nucis, conica, sed cono retro inclinato, acutis- 

 sima, alba, imbricata lamellis horizontaliter testam cingentibus. Margo 

 integer, ovalis, antrorsum gibbus s. dilatatus. Cavitas profunde glabra. 



This description very fairly suits the Patella antiquata of the twelfth 

 edition of the * Systema*. 



DENTALIUM. 



Testa univalvis, subcylindrica, utrinque aperta. Spira regularis nulla. 



Although the Serpulce were intermingled, it is clear that they did not 

 accord with the above definition. 



D. ELEPHANTiNUM. D. subulatum subarcuatum, angulatum. 



The synonymy of the tenth edition was appended. Lister excepted ; the 

 erroneous 13 of the reference to the Gazophylaceum was erased. Dens 

 elephantis was the proi)Osed trivial name.
