328 BRACHIOPODA OF THE 



Prof. Sedgwick J gives a list of the species which M'Coy thought he had been able to 

 identify, viz. : 



From Great Per aver, north of Gorran Haven. 



Orthis elegantula, Dolman. Said to be rare. I have not seen even a fragment 

 of the shell among the specimens preserved as having been examined by 

 M'Coy. 



— pauva, Pander. Said by M'Coy to be very abundant. I have no doubt 



that the specimens he referred to Pander's species were such as were after- 

 wards erroneously identified with Barrande's 0. redux, and to which we 

 have given the name of 0. Budleiyhensis. 



— calligramma (?), Dal. Is abundant where it is found. 



— turgida, M'Coy. Said by M'Coy to be very abundant; I have not seen it. 



It is doubtless a mistaken identification. 



— flabellulxim, Soio. Although stated by M'Coy to be very abundant, I 



have not noticed a single fragment of the species. 

 Calymene brevicapitata, Portlock. 



— parvifrons (?), Salter. 

 Homalonotus BisuLCATUS, Salter. 



From the Quartzite of the Great Cam. 

 Orthis testudinaria, Dal. Said to be abundant. It is doubtless the shell we 

 have named 0. Budleiyhensis. 



— retrorsistria, M'Coy. Said to be abundant. I have seen the specimens 



referred to, in the Cambridge Museum ; they belong to 0. Budleiyhensis. 



From near Forth Caerhays. 

 Orthis grandis (?), Sow. I believe this identification to be correct ; it is the 



Slrophomena yrandis, Sow. sp. 

 Cycloceras, sp. 



Prof. Sedgwick says : " All the above species (with the locality of each specimen 

 carefully recorded) are placed in the Museum at Penzance. . . . Specific names were 

 not affixed to many of the specimens ; and for the previous list I rest entirely on the 

 authority of Prof. M'Coy," 



After a very careful examination of all the specimens upon which Prof. M'Coy founded 

 his list, as now preserved in the Penzance and Truro Museums, I found only three, viz. 

 Orthis calliyramma, Orthis testudinaria or Budleiyhensis, and Strophomena grandis, that 

 were correct. 



The species are very few in number. I have recognised the following five only ; and
