81 MR. S. HANLEY ON THE LINNEAN MS. OF THE ' MUSEUM ULEICJ3.' 



H. coRNU-MiLiTARE. H. marginata imperforata subcarinata, labio 

 interiore explanato. 



The deceptive figure of Gualtieri was not at first cited. 



H. CORNEA. H. marginata convexa umbilicata, spira plana. 



** Faun. Suec. 1304 " was in place of the reference to * Lister's English 

 Conchology,' a work apparently unknown to our author when he first drew 

 up the Museum Catalogue. I doubt the identity of this shell (the intended 

 name for which was tahellaris) with the cornea of the * Systema.' 



H. coRNU-ARiETis. H. utriuquc depressa. 



'* List. Hist. t. 136. f. 40 " was written by our author in the manuscript 

 copy. 



H. AMPULLACEA. H, subrotunda, sursum ventricosior glabra. 



The original reading of " anfractus superne ventricosi " was " abdomen 

 superne ventrioosius ". The erroneous reference to Gaultieri was not at 

 first attached to the description. The species of the Museum was evidently 

 distinct from that of the ' Systema.' 



H. GLAUCA. H. subrotunda acuminata, labro postice marginato. 



H. ciTRiNA . H. umbilicata convexa obtusa. 



The final remark was an afterthought. 



H. ARBUSTORUM. H. marginata perforata convexo-acuminata, ore sub- 

 orbiculari, margine duplici, antice elongato. 



"Faun. Suec. 1295" was the only synonym; the work of Lister on 

 English Conchology not having been at first known to Linnaeus. 



H. UNGULINA. H. marginata perforata spiralis convexa, ore subor- 

 biculato. 



The " Gualt." was a misprint for the written " Rumph." 



H. LUTARIA. H. ovata-oblonga umbilicata, interne coloratiore. 



" Habitat frequens in lutosis fluviis, lacubus." May not the Valvata 

 piscinalis be the shell intended ? 



H. PERVERSA. H. ovato-oblonga subperforata glabra. 



"Pet. Gaz. t. 44. f. 7", and "Grew. Mus. t. 10. f.9'% citedin the *Sy- 

 stema', were also referred to in the MS. " Alba", and "in quibusdam ", 

 were interpolations in the Linnean handwriting : H. sulphur at a was the 

 intended designation. 



H. lANTHiNA. H. subrotunda obtusa patula diaphana. 



The entire account of this beautiful shell was written by Linnaeus sub- 

 sequently to the labours of his amanuensis : the twelve last printed words 

 were not present. The cited figure of Gualtieri was not admitted, as a re- 

 presentation, but only alluded to in the final remark of " Confer Gualt. 

 t. 64. f. O." " List. Hist, t, 572. f. 23", and " Sloan. Jam. 2. p. 239. t. 1. 

 f. 4 " were indicated as delineations. 



H. NEMORALIS. H. 



" Habitat ubique in Europae nemoribus ", and " Argen. t. 32. f. 8", were 

 the unprinted additions. Lister's English Conchology was not, of course, 

 mentioned. " Flavescens", and " nigro-purpurascens ", were not in the 

 original.
