III. — On the Disoovbet of a Species of Starfish in the Devonian 



Beds of South Devon. 



By Arthur Champernowne, M.A. 



THE only mention hitherto, so far as I know, of the occurrence 

 of Starfish in British Devonian rocks is that given by Mr. 

 Etheridge in his list of Devonian fossils (Quart. Journ. Geol. Soc, 

 vol. xxiii. p. 619), viz. Protaster, sp., and Palceaster, sp., from the 

 Pilton beds of North Devon ; therefore the discovery of a species in 

 South Devon rocks may not be without interest. 



The locality which yielded the few specimens in question is a 

 small quarry or road-side excavation at Inglebourne House, near 

 Harbertonford (about three miles S.S.W. of Totnes), in coarse slates 

 with one or two thin gritty layers, on one of which, forming part of 

 the floor of the quarry, were the impressions. The dip is about S.E. 

 (20° East of South Magnetic) at 15°, crossed by cleavage at a much 

 higher angle towards the South. The steady dip at this spot is con- 

 firmed by a small quarry in the adjoining field. 



Viewed in connexion with the Harbertonford limestone and the 

 slate quarry at Eoster Bridge, the beds would appear to belong to 

 the ZTpper South Devon series ; but of this it is difficult to speak with 

 certainty, owing to the fact that there is no limestone for some miles 

 west of Harbertonford. Its line of strike, however, appears to. pass 

 near the Eoster Bridge quarry south of the beds with the Starfish. 



The limestone at Harbertonford dips North at low angles, generally 

 not more than 10°, but close to the vicarage it is 25°. At Eoster Bridge, 

 where large Spirifers and other fossils are numerous, the cleavage 

 is the predominant feature ; but there also the true beds appear to dip 

 to the North. Possibly a fault passes between these and the beds at 

 Inglebourne, which dip S.E., the downthrow being to the North. 



I lately visited the locality in company with Mr. J. E. Lee and Mr. 

 Paige-Browne, of Inglebourne House, and the above was the view 

 taken by the latter, who considered the slates of Eoster Bridge quarry 

 as deeper in the series than the beds around his house, and the latter 

 as nearly on the horizon of the limestone, although I think they are 

 somewhat newer. Our search for Starfish was, however, fruitless. 



With regard to the specimens themselves, the best of which I 

 entrusted to my friend, Mr. J. E. Lee, to exhibit at the British 

 Association, Bradford, in September last, I am pleased to hear that 

 they are about to be described by Mr. Woodward, a more experienced 

 palaeontologist than myself. The object of the present note is merely 

 to record the fact of their occurrence, and give some account of the 

 locality.
