of the Edinburgh New Pliilosophical Journal. It may be satisfactory also to 

 state that Professor Harkness has informed Mr. Symonds, that among the dis- 

 coveries of Mr. Slimon, at Lesmahago, in Scotland, there are some trifids like Mr. 

 Lightbody's Phyllopod. 



He then informs me of discoveries of portions of the Pterygotus, which the 

 Ludlow Geologists have made, especially one which looked like a fish's tail 

 (membranaceous scaly above), together with some spines, which Mr. Salter con- 

 siders to be the end of one of the swimming limbs, also of a new kind, which 

 Salter calls Himanopterus punctatus. But I hope that he may himself be 

 prevailed upon to give us a paper on the subject of that, and of his other dis- 

 coveries, including the star fish af Leintwardine, and a " rara avis," which has 

 fallen in his way, Ascoceras Bohemicus, noted by Barrande in Bohemia, but never 

 until now found, or at least made known, as British. And in this hope, I shall 

 desist from further notice of the letter. 



Mr. Banks also most kindly responded to my request for information, by 

 sending me an account of the Scottish discoveries, and his own at Bradnor, but 

 as they have been published in the Society's reports, I must refer you to them 

 for fuller information than I can give, except by copying the whole report. He 

 has seen, and reports that the Scotch fossils are most instructive and interesting, 

 because in many instances the form of the animal is all but entire, while all the 

 peculiarities of form are remarkably preserved. He says, you may imagine how 

 perfect some of the specimens are, when I mention that, with the aid of a glass, 

 the pair of jaw feet in one specimen is seen with its inferior articulations in 

 working order ; and that, in most instances, the didactyle foot, with its pincer, 

 is entire. They occur on large slabs of a slaty material, and look like casts of 

 black sealing wax. Many of the portions, especially the jaw feet, resemble the 

 Pterygotus, and there is but little doubt entertained by Mr. Salter that the Himan- 

 opteri are closely allied to Pterygotus. 



Mr. Banks also informs me that his cephalaspis-like heads have, with C. 

 Lewisii and Lloydii, been provisionally styled Pteraspis. To this I may add that 

 I have found some good specimens in the Leysters beds, as well as a portion of a 

 head, but perhaps of a different species from the Lower Ludlow at Leintwardine. 

 This fact seemed curious enough to warrant my mentioning it here. 



I may mention that the Meteorological observations of the Club have been 

 continued under Mr. Wheatley's superintendence, and I think you will agree with 

 me, that our thanks are eminently due to him for the pains which he has taken 

 in that department. 



As regards the Zoology of the county, I know not that I have much to say. 

 I have seen by the papers that a specimen of the Red-throated or speckled Diver 

 has been taken near Ross, and in my own parish, a pair of the Anas clypeata, or 

 Shoveler duck, and a Green Sandpiper are the principal strangers, if indeed they 

 £u:e strangers.
