COEALLIAN EOCKS OF UPWARE.

their kindness in carefully examining and measuring the well- 

 section at Upware, and in collecting specimens, at some personal 

 inconvenience ; to Mr. H. Keeping, of the Woodwardian Museum, 

 for the trouble that he has taken in examining the well and in 

 tracing the further extension of the Elsworth and Upware lime- 

 stones, also for allowing me to examine the large series of fossils 

 which he has obtained from both rocks ; to Dr. G. J. Hinde, for 

 kindly examining certain sponges from Upware ; to Mr. F. Chapman, 

 who was good enough to give his opinion on certain foraminifera ; 

 and to Mr. J. E. Marr for much valuable advice. 



Note on certain Corallian Fossils from Upware. 



The small exposure of ' E-ag ' in the Southern Quarry has been 

 for many years so carefully searched for fossils by many geologists 

 that few new forms are likely to be found, except perhaps among 

 the foraminifera. To the fauna of the ' Kag ' proper the present 

 writer is able to add only one form, a tooth of Hyhodus ; this, 

 however, is interesting as being, so far as known, the only vertebrate 

 yet found at Upware. H, grossiconus has been recorded from the 

 Elsworth and St. Ives Eock. 



Besides this, the sponge recorded by Roberts from the ' Rag ' as 

 Scyphia sp. proves to be Holcospongia glomerata (Quenst.). I 

 have found this species in both the Rag and the oolite, and in 

 the section near the Inn. Thinking that other species of Holco- 

 spongia might be represented, I submitted specimens to Dr. G. J. 

 Hinde, who was good enough to examine them, and considers them 

 all to be H. glomerata, except perhaps one specimen. 



In the series of fossils obtained by Mr. Keeping from the highest 

 beds of oolite in the Southern Quarry, beds which have been 

 neither so long exposed nor so frequently worked, there occur a few 

 forms new to Upware, namely : — 



Pecten : an internal cast of a rather large species, showing traces of strong 

 concentric marking as well as numerous ribs ; it resembles somewhat 

 P. annulatus. 



Trichites sp. 



Opis, large sp. (not 0. virdunensis) : an unnamed specimen of apparently 

 the same species, from the Rag, is in the Woodwardian Museum. 



Waldheimia sp. 



The following, previously recorded from the ' Rag,' have been 

 obtained by me from the Northern Quarry oolite : — 



Eryma sp. (?). 



Ammonites {Cardioceras) vertebralis, 



var. cawtonensis, Bl. & H. 

 Bentalium sp. 

 Exogyra nana, Sow. 



Gervillia sp. 



Ostrea sp. 



Vermilia sulcata, Sow. 



Holcospongia glomerata (Quenst.). 



In the field-section near the Inn, from the limestone with ' Rag '- 

 fossils (bed 4 of the section) Holcospongia glomerata (Quenst.), 

 Holcospongia, another sp. ?, and Vaginulina legumen ? (or Dentalina
