"The tail and body of this fish are as yet unknown/' and I beheve they ren,a,ned 

 unknown until the 16th March. 1882, when I found at Ledbury, m one of the 

 Silurian bands of the Passage Beds, a head plate with a few body -"^^^^ ' 

 since that time I have discovered three tolerably perfect fish xn a true Red Sand^ 

 stone hand, many feet below the Ledbury Auchenasp.s gnts, where the head 

 plates were first seen. These fish now form part of my collection, and are, I 

 b 1 eve, the only specimens extant. I am not aware that Auchenasp.s has been 

 found dsewhere than at Ledbury and Ludlow, unless the solitary specimen, from 

 the Passage Beds at Trimpley, near Kidderminster, which is some 2^ inches acro^ 

 the head plate-it has no body-and may be seen at Jermyn Street Museum, is 

 really an Auchenaspis. But if the generic name of that particular specimen is 

 correct, I do not think the specific one can possibly, be so. I have also found in 

 these beds some magnificent specimens of Ceph.laspidean Fishes, one of which 

 has been pronounced by Dr. Woodward, L.L.D., F.R.S F..;.S.. &c.. ancl Mr^ 

 William Davies, F.G.S., of the British Museum, and South Kensington, to be of a 

 new species The beds have also yielded large thoracic and abdominal segments 

 of two or more species of Pterygotus, and many other objects of interest. During 

 the construction of the Ledbury railway, some 25 years ago, Henry Brookes found 

 some dwarfed specimens of Pentamerus Knightii in blocks of Aymestry limestone 

 brought out of the tunnel. Since that time he and I have frequently sought for 

 the band on the surface, but without success. In the spring of last year I hit 

 upon it at a distance of 27 feet from the south east corner of the Frith wood, and 

 found that it nowhere exceeded two inches in thickness, and that the largest fos- 

 sils did not reach the size of a florin, the whole forming a remarkable contrast to 

 the noble development of this formation, and its huge fossils, as seen in the great 

 quarry at the back of Aymestry village. Another find of some importance occur- 

 red last year in the little cutting, then newly made, to connect the station yard 

 with the Silurian quarry, whence ballast is obtained for the surface of the railway 

 now in course of construction between Ledbury and Gloucester. Mr. Symonds 

 has long lamented that the "Bone Bed" has not been seen at Ledbury: but soon 

 after the cutting in question was opened, I succeeded in finding the true Bone 

 Bed in its proper position at the top of the upper Ludlow series. It may be ob- 

 served a few yards below the wooden bridge which joins Reddings Hole to the 

 Frith, and is most conspicuous on the north side. 



After a due examination of the Passage Beds proper, the succeeding series of 

 Downton Sandstone, upper, middle, and lower Ludlow were visited, where many 

 men were engaged in getting ballast for the railway. In the earlier stages of 

 the work, hundreds of tons of the lower Ludlow Formation were sent away for 

 this purpose, all of which, if subjected to the ordinary sub-aenal influences, will 

 inevitably become mud within two years after exposure. I presume tho^ m 

 authority have at last discovered the inutility of this material for the purpose to 

 which it was applied, as they have ceased to use it, and now employ the Aymestry 

 limestone only. It must be admitted that these formations in situ differ little 

 in external appearance, and are so commingled in this particular section that I 

 have felt compelled to allot nine feet as passage beds, for here there is no true line
