216 Miscellanies. 



this artist, illustrative of Coleridge's Ancient Mariner, which met the de 

 cided approbation of the author of the ballad. There is great muscu- 

 lar and intellectual character in these designs ; indeed, Mr. Scott is said to 

 have sacrificed much to form and character, foregoing the soft and beau- 

 tiful contrasts which are generally more delightful. In the Art Union, of 

 London, a paper devoted to the fine arts, the intellectual power of Mr. 

 Scott's productions is fully appreciated. Among his late works, the 

 Alchymist is distinguished. " The wily professor is swinging back in 

 his chair amidst a crowd of votaries worthy of Chaucer's fancy, and 

 holding in his hand some redoubtable elixir, whose virtues, known and 

 unknown, are sufficiently impressed on the arch chemist's countenance." 

 The Parthian Archer is a figure of great force, and the splendid bow 

 which he holds bent, with the arrow drawn to its head and ready to let 

 fly, is after the representations of the Parthian bow found on ancient 

 vases. A drawing of it was furnished, last winter, to Mr. Dunlop, by 

 Sir John Macniel, late ambassador to Persia. The bow is bent back- 

 ward, and when unstrung takes the form of a C : " there is therefore 

 more power exerted in the flexion than is apparent to the eye." The 

 admirer of Young's Night Thoughts will recollect the allusion respect- 

 ing our past thoughts and actions — 



" Whose yesterdays look backward with a smile, 

 Nor like the Parthian wound him as they fly." 



23. Correction. — Messrs. Editors : Since writing my article upon the 

 Melanians, (Vol. xli, p. 21,) I have been able to examine living indi- 

 viduals of Melania undulata. Say ; and find that it is not congeneric with 

 Nerita aurita, MiilL, as I supposed from a comparison of the shells. 

 The former is a true Melania, whilst the latter belongs to the Cerithidas, 

 of which it constitutes a new genus, next to Potamis. 



• Genus Claviger. Shell like Melania, but with a sinuated labrum, 

 and a sinus at its junction v;ith the columella. Type, C. aurita : icon. 

 Guerin's Mag. pi. 12 and 13, the latter being C. tuberculosa. The 

 characters of the animal are those given to Melania by Deshayes in 

 his edition of Lamarck, Vol. VIII, p. 427, 8. 



Genus Teochlea. I propose this name for the genus of shells call- 

 ed Planaria by Capt. Brown, the latter being preoccupied in zoology.
