Morgan Expeditions. 127 



Dedicated to Mr. Eolfe Eldredge, one of Prof. Hartt's 

 companions at Erere, on his expedition of 1870. 



Anion <? the more obscure remains obtained from the De- 

 vonian sandstone beds at Erere, and which it is impossible 

 from their imperfect condition to properly identify, are frag- 

 ments of crinoidal columns, the valves of a form which 

 appears to be related to jBeyrichia, M'Coy, fragments of 

 wood, etc. They are all, however, in such a poor state of 

 preservation, that it would be unwise to attempt anything 

 beyond a mere notice of their appearance. The crinoidal 

 remains occur as impressions of the detached disks of the 

 columns, which are small and thin, and it is seldom that more 

 than two or three of the disks are found together. The 

 central canal is generally replaced by sandy material, but 

 none of the surface markings are retained. Diameter of 

 disks, about 2-5 to 3 mm ; thickness of each, about -5 mm . The 

 test of Beyrichia ( ?) is small, sub-ovate in outline, with a 

 slight depression near one end. The surface, though imper- 

 fect in all the specimens obtained, seems to have been granu- 

 lose. Diameter of a medium specimen, 2 mm . The remains 

 that have been referred to with doubt as plants have no 

 definite or describable shapes and are probably fucoidal. 

 Many of the other fragments obtained will undoubtedly be 

 explained with the aid of new collections from the same 

 locality.
