MYXOSTOMA PIDIENSE. 133 



I did not find any specimens of this species in the United States 

 National Mnseuiu. The types of vclatus and collapsus, preserved in the 

 Museum of the Academy of Natural Sciences, at Philadelphia, I have 

 examined.

Habitat. — Kansas to Texas. 



The original type of congestus, No. 171, from Eio Salado, Texas, col- 

 lected in 1851 by John H. Clark, seems to have disappeared from the 

 Museum. No description of the mouth has been given, except that it is 

 "very small". The species, therefore, probably" has a mouth similar to 

 that of velatum, and, if so, is probably identical with the species since 

 described as P. hucco by Professor Coi)e. I have not seen the type of 

 P. bucco, and, therefore, can only suggest the probable identity of the 

 two ; but, as the matter is likely to remain long unsettled, it seems best 

 ])rovisionally to unite them. "P. congestus'''' Cope «So Yarrow is certainly 

 not this species ; more likely a form of M. macrolepidotum. 



17. MYXOSTOMA PIDIENSE {Cope) Jordan. 



Mullet of the Great Pedee. 



1870 — Ptychostomus pidiensis Cope, Proc. Am. Philos. Soc. Phila. 471. 



Teretulus pidiensis Jordan & Copeland, Check List, 158, 1876. (Name ouly.) 

 Myxostovia pidiensis Jordan, Man. Vert. ed. 2d, 317, 1878. 



Habitat. — Great Pedee River, North Carolina. 



This appears to be a slender species, resembling "P, cervinus in color, 

 form, and size". Professor Cope obtained it in the Yadkin River. I 

 have not seen it. No specimens are in the National Museum.
