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 longitu- 

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

 by Linnaeus) was not to Gualtieri, but to Lister, 335, f. 172, 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. Vho. 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 reliquse " follows " orbiculata," and in place of " In area 

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

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



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



The incorrect figure of d*Argenville was not indicated. 



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



V. LiTERATA. CJia. trausversim striato-ovata. 



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

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



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



The printed additions are " varius in 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. subcordatus laevis lateribusrugosis. 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. macrodon answers fairly enough to this definition.
