operations of the Devon Iron Company, and in the neighbourhood 

 of their works." The specimen consisted of a portion of an indi- 

 vidual exhibiting both sides of the body, with a large number 

 of scales in position, which were recognized by Dr. Fleming as 

 " the scales of a fish." The specimen, when slit horizontally, 

 exhibited the remains of the vertebral column. Upon my calling 

 the attention of Dr. R. H. Traquair to this paper, he at once 

 recognized in the figures an unlabelled specimen of M. Hibberti in 

 the Museum of Science and Art, Edinburgh, but which he had 

 long surmised formed a portion of the " Fleming Collection," de- 

 posited in that institution. The genus Megalichthys had been 

 established previously by Prof. Agassiz (Brit. Assoc. Eeport for 1834, 

 p. 448), and the species M. Hibberti indicated in a foot-note attached 

 to the paper in question, " On the Fossil Fishes of Scotland." 



3. CoEBULA LiMOSA, Fleming (Brit. Animals, 1828, p. 426). — The 

 type specimens of this species are preserved in the " Fleming 

 Collection," Museum of Science and Art, Edinburgh, and are from 

 " slate-clay connected with Carboniferous Limestone." C. laminosa 

 appears to have been entirely lost sight of by subsequent writers, 

 except Prof. Morris (Cat. Brit. Foss., second ed. 1854, p. 195). I 

 am at present in doubt as to the true generic relations of the species, 

 but it is not unlikely that it may prove to be a ScJiizodus, or closely 

 allied genus. It has the anteriorly incurved beaks of the former. 



4. Venerupis Ltelli, Fleming (MS.). — There is also in the 

 above collection a very fine Carboniferous bivalve bearing a label 

 with the above name. So far as I know. Prof. Fleming did not 

 publish a description of it, and I do not find it mentioned in any 

 list. It is a large Edmondiform shell, apparently near Edmondia 

 Tiidis, M'Coy; E. gibbosa, M'Coy ; E. quadrata, M'Coy, or E. 

 oblonga, M'Coy. I hope to describe it fully. 



6. Pleukotomarta humilis, de Koninck (Foss. Pal. Nouv. Galles 

 du Sud, 1877, pt. 3, p. 325, t. 23, f. 14).— A new form of Pleiiro- 

 tomaria was shown me by Mr. John Henderson (Edinb. Geol. Soc), 

 obtained by him at the Gilmerton Quarry, near Edinburgh. Upon 

 forwarding it to Prof, de Koninck, the latter was kind enough to 

 inform me it was his P. humilis, a new form then in course of 

 description from the Rev. W. B. Clarke's collection of N. S. Wales 

 Carboniferous fossils. It has since been published in the above 

 work. The discovery of this species by Mr. Henderson in our 

 Lower Carboniferous Limestone Group is a fact worthy of record. 



6. AscoDiCTYON stellatum, Nicliolson and Etheridge, jun. (Ann. 

 Nat. Hist. 1877, vol. xx. p. 464, t. 19, f. 1-6).— The British species 

 of this provisional genus was A. radiatum, N. and E. Evidence has 

 now been obtained by Mr. J. Bennie, which will probably indicate 

 A. stellatum, N. and E., also as British. A fragment of a Crinoidal 

 stem has scattered over it a number of vesicles united by creeping 

 stolons or fibres, so closely resembling those figured by Prof 

 Nicholson and myself as the oval young (?) vesicles of this species, 

 that I see no reason, so far as the evidence at my command goes, to 

 doubt the identity of the forms.
