 ' On Footprinta from the Permian of Munalield (Nottinghamshire).' 

 By George Hiekling, B.Sc. 



Tlieso fossils were discovered in 1897 by Mr. Francis Holmes in 

 the Rock-Vulley Quarry, Mansfield, in a local, lenticular, mass of 

 sandstone intercalated in the Magnesian Limestone. The impressions 

 formed two double rows, approximately parallel, and 7 and 2 feet 

 long respectively. Nearly the whole of the longer series is in the 

 Nottingham Museum, and part of the shorter series in the Manchester 

 Museum. Both sets were made by the same species of animal, the 

 stride in one case being 8, and in the other 8j inches. The prints 

 show a well-marked heel and comparatively-slender digits, and 

 there is evidence of a membrane between the toes. There is wide 

 separation between the right and left sides, this separation being 

 more marked in the fore than in the hinder footprints. The prints 

 present some resemblance to those named Ichniiun acrodaclylum, 

 from the Uj)per Permian of Tluiriiigia. Recently the Author has 

 found other prints in the same quarry. 



MISCELLANEOUS. 

 The Echinodenn Name Calveria hystrix. By F. A. Batuer. 

 In their " Preliminary Report of the Scientific Exploration of the 

 Deep-Sea in H.M.S. 'Porcupine,' during the Summer of 1869" 

 (Proc. Roy. Soc. xviii. pp. 397-492; ltt7u, ? June), W. B. Carpenter, 

 J. Gwyn Jeffreys, and Wyville Thomson, describing the echinoderm 

 fauna of the Cold area, wrote as follows (p. 445): — "In the 

 Shetland channel we procured a full-sized specimen of the remarkable 

 Clypeastroid PDurtaJemi, of which young exaniiiles had been 

 obtained in the First cruise, and a very singular Asterid allied to 

 Pteraster, which is covered with a regular brush of long paxillfe. 

 Since, for the reason formerly mentioned, we have found ourselves 

 precluded from dedicating the former of these types (as we had 

 intended) to our friend Capt. Calver. we propose to give the generic 

 name Caheria to the latter, with the specific designation Jn/strix." 

 " The reason formerly mentioned " was that the same Echinnid had 

 shortly before been discovered by Pourtales in the Gulf of Mexiio 

 and had been described by Prof A. Agassi/, under the name 

 Pourtalesia miranda (see same Report, p. 421). 



The next occurrence of the name C(dvcria hystrix is in " Report 

 on Deep-sea Researches .... during .... 1870 in ILM.S. 

 ' Porcupine,'" by \V. B. Carpenter and J. Gwyn Jeffreys (Proc. Roy. 

 Soc. xix. pp. 146-221 ; 1871 [prol)ably February or March^). 

 On p. 1.54 the authors write: — "Thursday, July 14, passed Cape 

 Finisterre and dredged in 81 fathoms (Station lU), about nine 

 miles from the coast of Spain. . . . "VVe then steamed out, and 

 dredged in 332 fathoms (Station 11). . . . On the tangles were
