LIST OF RECENT BRACHIOPODA—DALL. 



319 



No. 64255 was submitted to Mr. Davidson and pronounced to be 

 his T. moseleyi, agreeing very closely with his figures in the Challenger 

 report. The other specimens appear to be conspecific, though the 

 Panama specimens are dead and dilapidated valves. The older 

 specimens show three marked short grooves separated by the mus- 

 cular impressions which are more or less raised, in the pedicel valve, 

 and in senile specimens these are quite deep. 



There has been some doubt expressed as to the identity of the above 

 specimens with the species dredged at Kerguelen, notwithstanding 

 their agreement in the external features. I confess to some doubt 

 myself and would suggest for the species in case they prove distinct 

 the name of Gryphus martinicensis, the specimen numbered 64255 

 being taken as type. 



GRYPHUS TOKIONIS, new species. 



TerebratuU? Davidson, Proc. Zool. Soc, 1871, p. 312, pi. 31, fig. 6. 

 Type locality. — U. S. Bureau of Fisheries station 3661, in the Gulf 

 of Tokio, Japan, in 169 fathoms, mud, bottom temperature 48° F. 



The brachial valve is subcircular, the loop short, rather wide, the 

 parts narrow, the lower portion slightly elevated mesially, the ante- 

 rior corners angular and sharply pointed, the crura short and blunt, 

 the plates deeply excavated, completely separated with a small 

 prominent rugose cardinal process. There is a faint ridge between 

 the muscular impressions, in the brachial valve, and another in the 

 pedicel valve. The exterior is smooth, the foramen entire, there is 

 a well marked "collar" within the foramen. 



Mr. Davidson had a specimen of this species which he figured in 

 his paper on Japanese brachiopods above cited. He did not describe 

 it because the cardinalia were defective and he was doubtful about 

 the genus. I have seen no subsequent reference to it.
