of papilUe ; 4 to 6 in specimens from eastern Colorado, (var. sucklii). 

 Scales crowded anteriorly, nuicli larger on the sides than below ; scales 

 10-64 to 70-9. Coloration olivaceous ; males in spring with a faint rosy 

 lateral band ; young brownish, more or less mottled, often with conlluent 

 blackish lateral blotches or a lateral baud. Lateral lino imperfect in the 

 very young. D. usually 12. L. 18 inches. Streams and ponds from 

 Quebec and the Great Lakes to Montana, Colorado, and southward to 

 Missouri and Georgia ; the commonest of the suckers, excessively abund- 

 ant from Massachusetts west to Kansas. Variable ; western specimens 

 (suchUi) have broader li[)s and approach ('. Jrdciis. (To Philebert Com- 

 merson, an able early French naturalist and traveler, whose collections 

 were studied by Laci5pede.)

*The Cyprinus commersonii of Lacepede is a sucker and probably this species rather than C. 

 catostomus. The description is, however, very imperfect and the type said to have been observed 

 by Commerson in the East Indies; a statement apparently derived from a confusion of manu- 

 scripts and specimens of Commerson with those of Bosc, who collected at Charleston. Lace(iode 

 was indebted to Bo.sc for the next species he mentions, Ci/prinus sucetta. Lacepe<le'8 description 

 is as follows: "Onze rayons il la dorsale; sept il la nageoire de I'anus; ueuf a cha(|ue ventrale; 

 huit a neuf iV'chaquo pectorale; la nageoire du dos et celle de I'anus quadrilatires; Tunalo 

 etroite; Tangle de rextremito do cetto derniere nageoire tresaigu; la caudale en croissant; la 

 ligne lateralo droite; la machoire superieure, un pen plus avancee que celle d'en bas; les Ocailles 

 arrondies ot tres petites. Lo Commersonuien dont nous publions lea premiers la description, 

 et que le eavant Commerson a observe, presento un double orifice pour chacjue narine; sa teto 

 estdenouee de petites ecailles; ees ventrales et pes pectoralcs sont arrondies il leur extremite; la 

 dorsale s'eleve vers le milieu de la longueur totale du poisson." 



fThe small "Juno sucker" of the Adirondacks thus described by Matlier : "Olivaceous, white 

 below; males without red in the breeding season; body slender; head not small, llattened 

 above; snout little prominent; upper lip with 2 rows of' papilhv; eye 4 in lieud, 2 in snout; 

 dorsal as long as high; pectorals nearly reaching front of dorsal; head 4. 1). I, 11 ; A. 5 ; V. 9. 

 Scales 9-6 7-8; length of adult 4;,^ inches, liiue Mountain Lakes, Adirondack region. This 

 small fish I was at first disposed to consider as a dwarfed mountain form of C. teres, but the fact 

 that the latter fish is found in waters inhabited by this species, and while it grows to a length 

 of 12 or more inches there, this little sucker barely reaches ,5. Added to this the fact that 

 the larger species had finished spawning in the inlets in May, while this fish was found in 

 masses in the swift mountaiu streams which tumble rapidly over rocks in the latter part of 

 June, depositing their eggs, thereby showing that they are adult fish."
