MYXOSTOMA PIDIENSE. 133 



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

 National Museum. The types of velatus and collapsus, i)reserved in the 

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

 examined. 



16. MYXOSTOMA CONGESTUM {Baird & Girard) Jordan. 



Gibious SucTcer. •

Teretulus bucco Jordan & Copeland, Check List, 157, 1876. (Name only.) 



Habitat. — Kansas to Texas. 



The original type of congestus, Ko. 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 Cope. I have not seen the type of 

 P. Micco, 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 & Yarrow is certainly 

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



17. MYXOSTOMA PIDIENSE (Cope) Jordan. 



Mullet of the Great Fedee. 



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



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

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



Habitat. — Great Pedes 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 Eiver. I 

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