MB. S. HANLET ON THE LINNEAN MS. OF THE ' MUSEUM ULRICA.' 53 



The original synonymy and details have been so transmuted in the press, 



that it is manifest that the amended (!) species was perfectly distinct from 



the shell originally designed. The name of the latter was clathrata, and 



the declared sculpture was not merely " transversim," but " et lon^itu- 



dinaliter " likewise (in place of " striis retrorsis "). The reference (added 



by Linnaeus) was not to Gualtieri, but to Lister, 335, f. 1/2, and its copy 



in Klein (t. 10. f. 52), both which would have more appropriately been 



assigned to V. reticulata. The V. exoleta having been previously defined 



in the ' Systema,' this confusion becomes of little importance. 



V. ziczAC. ¥ho. striis transversis membranaceis erectis. 



The number which indicates the position of this species in the ' Museum ' 



has been subsequently ('Syst.' ed. 12) referred to V. cancellata, yet, 



judging from the generic appellation (and consequent dentition), it could 



scarcely have been that well-known species. The " lentiformi " of the 



•Systema' (ed. 10), where the name ziczac first appeared, forbids the 



annexation ; but, although the details of the ' Museum ' were there referred 



to, the obnoxious word was not mentioned in that publication. The 



following are the printed emendations (?) : " laevis, et quasi excisa," " com- 



pressa,'' " variat colore albissimo." 



V. PECTIN ATA. Pho. sulcis longitudiualibus nodosis, antice antror- 

 sum ramosa. 



The additional synonym of " Gualt. D. 75, f. A. " appears in the MS., 

 where " quam reliquae " follows " orbiculata," and in place of " In area 

 antica " may be read " et a primo sulco." The details there terminate 

 with the word "lanceolatum." " Ramosa " was the intended name. 

 V. SCRIPTA. Pho. striata, postice angulo recto circumscripta. 

 The incorrect figure of d'Argenville was not indicated. 

 V. EDENTULA. Pho. subgloboso-lenticulata rugosa edentula. 

 V. LiTERATA. Cha. transversim striato-ovata. 



The earlier reading of confertim was " profunde " ; " striis crenulatis 

 antice et postice," " lanceolata," and "tres s." were absent. 



V. ROTUNDATA. Cha. trausvcrsim striata ovata absque angulo. 

 The printed additions are "variusin variis," "aut albis," " lanceolata," 

 and the final remark. There was no name attached in the MS. 

 V. DECUSSATA. Cha. testa ovata, decussatim striata. 

 " Ssepe " and " minimus " are the sole printed additions. 



Probably the V. Phryne of the ' Systema ' was designed by the following 

 unpublished description : — 



CuN. VENOSUS. C. subcordatuslaevislateribusrugosis. Testa cinerea, 

 nuce coryli major, gibba, glabra, antice et postice transversim sulcata. 

 Margo exterius tantum denticulatus, non vero apex externus, aut margines 

 laterales. 



The V. rnacrodon answers fairly enough to this definition.
