Fishes of the Order Cyprinodontes 13 



III 



Four or more species of Profundulus may be distinguished. Two are 

 from the Atlantic, the others from the Pacific drainage of Central America. 



I. Profundulus punctatus Giinther 



Fundulus punctatus Giinther, Cat. Fishes Brit. Mus., 6, 1866, p. 320 (original 

 description; page priority over guatcmalensis) ; Trans. Zool. Soc. London, 6, 1868, 

 p. 482, pi. 84. fig. 5 (redescription of types, with figure) ; Jordan and Evermann, Bull. 

 U. S. Nat. Mus., 47, pt. I. 1896, p. 637 (after Giinther) ; Meek, Publ. Field Mus. 

 (Zool.), 5, 1904, p. 104; ibid., 7, 1907, p. 136; Regan, Biol. Gentr. Am., Pisces, 1907, 

 p. 78 (excepting oaxacac in synonymy) ; Fowler, Proc. Acad. Nat. Sci. Phila., 68, 

 1916, p. 47. 



Fundulus guatcmalensis Giinther, Cat. Fishes Brit. Mus., 6, 1886, p. 321 (original 

 description) ; Trans. Zool. Soc. London, 6, 1868, p. 482, pi. 84, figs. 3, 4 (redescription 

 of types, with figures); Meek, Publ. Field Mus. (Zool.), 5, 1904, p. 103; ibid., 7, 1907, 

 pp. 136, 184. 



f Fundulus guatemalcnsis Eigenmann, Proc. U. S. Nat. Mus., 13, 1891, p. 64 

 (Western Ecuador; locality probably erroneous). 



Adfitiia guatcmalensis Jordan and Evermann, Bull. U. S. Nat. Mus., 47, pt. i, 1896, 

 p. 660 (punctatus was here retained in Fundulus!). 



Zoogoncticus guatcmalensis Meek, Publ. Field Mus. (Zool.), 3, 1903, p. 94 (name 

 only; the species erroneously and uncritically placed in the unrelated new genus 

 Zoogoncticus). 



Fundulus pachycephalus Giinther, Cat. Fishes Brit. Mus., 6, 1866, p. 321 (a doubtful 

 synonym of punctatus, which has page priority) ; Trans. Zool. Soc. London, 6, 1868, 

 p. 483, pi. 84, fig. 6 (type figure and redescription of type) ; Regan, Biol. Centr. Am., 

 Pisces, 1907, p. 77. 



Fundulus parvipinnis Garman, Mem. Mus. Comp. Zool., 19, 1895, p. 100 (in part: 

 Profundulus punctatus confused with Fundulus parvipinnis !). 



Specimens collected by George P. Engelhardt in the Rio de Moka, Guate- 

 mala, were identified with this species by Dr. S. E. Meek, but the record was 

 never published. All of the material published on by Dr. Meek (see syn- 

 onymy) has been re-examined. I provisionally follow Regan in uniting the 

 nominal forms guatemalensis and punctatus under one specific name. The 

 specimens at hand from (the outlet of) Lake Amatitlan, regarded by Meek 

 as typical of guatemalcnsis, are, it is true, of stouter build and paler colora- 

 tion than stream specimens (typical punctatus) . But some of the specimens 

 from the outlet of the lake show evident, though indistinct, spots on the 

 dorsal and caudal fins, and closely resemble the type of punctatus in the form 

 and general coloration of the body. The degree of spotting is also very vari- 

 able in stream specimens. Hence it is provisionally assumed that the name 

 guatemalcnsis was based on well-nourished, pale-colored lake specimens of 

 punctatus, and that the form is at most only racially distinct.
