<strong>Morphological variation within the California killifish, <em>Fundulus</em> <em>parvipinnis</em> Girard, 1854 from Baja California peninsula, Mexico (Cyprinodontiformes: Fundulidae), with elevation of its southern subspecies to <em>F. brevis</em> Osburn & Nichols, 1916</strong>

We evaluated the morphological variation of the two nominal subspecies of California killifishes, Fundulus parvipinnis ( F. p. parvipinnis and F. p. brevis ) with allopatric distribution in the Baja California peninsula, Mexico. Fifty-five morphological characters (10 meristic and 45 morphometric) of 192 specimens were examined in 10 populations (seven of F. p. parvipinnis and three of F. p.…
