Afler the Appendix was in type, I met with descriptions of sc,·eral ncw species which hare appcarecl in a local de5- criptire catalogue "of the l\1ollnscous Animals of the Coun- t_ics of Abcrdeen, Kincardine, ancl Danlf, by Profcssor l\facgil- livray." Although I hnve not implicit faith in the accmacy of that gentleman's conchological obsen•ations, arising from a Jlcrusnl of his work, yet I am unwilling to withhold the notice of species which ma9 tnrn out lo be new. In justifrcation of what I have said, I shall simply point out onc, a111ong many inaccuracies in the work refcrred to. The Profcssor, in dcscribing Cn1ssina compi·essa, says " this specics ~ornes nearest in form to (Astarte) Crassi1w clliptica; but has little aflinity to Cmssi,w multicostata, which lrns by severa! authors bce11 strangely confouncled with it." Now, with respect 10 its FORM being nearest to C. r.lliptica, I consider thesc two ~rccics are more dissimilar in fann than any other of the Ilritish 2 I Crassinro; as will be seen by comparing C. elliptica, fig. 3, anti C. comp,·essa, fig. 1, 4, 5, pi. XXXVIII, of this work. I carc- fully drew ancl clcscribcd thc original shcll of thc !alter spccie~, from which that accurate obsen•er of Naturc, Colonel Montagu, made his clescripli on. But afterwarcls meeting with thc fine specimen, formerly the property of Captain Laskey, in the cabinct of the late David Falconer, Esq., of Carlowric, I sub- stitutecl it for the <lrawing I made from the collcction of Colonel Montagu, in thc Dritish Muscum. I am ccrtai11 of its accuracy, so that lhe shcll which l\facgillivray describes cannot poss?bly be the C. com¡n-css<1 of l\fontagu. In allusion to this samc shell, the Profossor "strangely confounds" two shells, :md refcrs to a species which is totally clistinct;-hc says, "Brown's C1-.1ssiiw sulcata. (pl. XVIII, fig. 10, of First E<lition, an<l pl. XXXVIII. of the present) cannot be Montagu's Venus s-ttlcata, the margin in thc former being crenate, in the latter plain."
