Pleurolepis asprellus Jordan, 1878, Bull. Illinois State Lab. Nat. 

 Hist., vol. 1, no. 2, p. 38. 



Holotype: INHS uncat. (1, 90), Illinois, Hancock Co., small 

 rocky trib. of Mississippi R.; C. K. Worthen. 



Para types: ?(1, ?), same data as holotype. ? Illinois, Effingham 

 Co., Little Wabash R.; S. A. Forbes; July 1877. We have been 

 unable to find any paratypes of this species. The types were orig- 

 inally in the collection of the IlHnois State Laboratory of Natural 

 History. Smith and Bridges (1960, p. 254) did not list any type 

 material of this species in the collections of the Illinois Natural 

 History Survey which is the State Laboratory's successor, but 

 Dr. Smith recently found the holotype for us. 



= Ammocrypta {Crystallaria) asprella (Jordan). 



Pleurolepis pellucidus Agassiz in Putnam, 1863, Bull. Mus. Comp. 

 Zool., vol. 1, p. 5. 



Lectotype: USNM 1311 (1, 50), Ohio, Black R., below falls at 

 Elyria; S. F. Baird; August 1853; orig. no. 17. USNM 1311, then 

 containing 21 specimens, was listed as type by Jordan and Evermann 

 (1896, p. 1063); Linder (1959, p. 182) selected 1 specimen as lectotype. 



Paralec to types: USNM 164165 (20, 40-48) removed from USNM 

 1311 by Linder (1959). MCZ 24616 (9, 30-47) and UMMZ 86489 

 (3, 47-50) orig. out of USNM 1311, then MCZ 270. Although not 

 mentioned by Jordan and Evermann or Linder, these collections are 

 obviously part of the original material and come from the type locaUty 

 and so must be considered parlec to types. 



There is no mention of any localities in the original description of 

 P. pellucidus, but the following specimens were probably part of the 

 original material. USNM 1289 (1, 49), Michigan, Port Huron; 

 Baird; August 1853. USNM 1295 (1, 39), Mich., Detroit R.; Baird; 

 August 1853. MCZ 24626 (4, 44-49) and UMMZ 86479 (1, 46), 

 Ohio, Rockport; Kirtland. 



=Ammocrypta (Ammocrypta) piMucida (Agassiz) not A. pellucida 

 (Baird) as frequently given because the Baird name was Hsted as a 

 synonym in Putnam and therefore has no status. 



Poecilichthys artesiae Hay, 1881, Proc. U.S. Nat. Mus., vol. 3, p. 494. 



Holotype: USNM 27434 (d^, 63), Mississippi, Lowndes Co., 

 Catawba Cr., trib. of Tombigbee R. at Artesia; O. P. Hay; March- 

 April 1880.
