946. FUNDULUS RATHBUNI, Jordan & Meek. 



Head 3| ; depth 4i; eye 3f. D. 11; A. 11; scales 38-12. Body 

 moderately elongate, rather robust, iittle compressed; the back broad, 

 not elevated. Head moderately broad and depressed above; snout 

 rather sharp, as long as eye; scales of medium size, the humeral scale 

 not enlarged; 2 rows of scales on cheek. Fins all low and small ; dorsal 

 inserted posteriorly, its first ray opposite first of anal or slightly behind 

 it; longest ray of dorsal If in head; anal larger than dorsal; pec- 

 toral short, 1| in head; ventrals very short, reaching vent. Coloration 

 in life pale green, with small, irregular, horizontally oblong dark brown 

 spots scattered over head and body. Sexes not very different. Males 

 with scales of body edged with black and with a pale lengthwise streak 

 along upper part of each row of scales. Young with very obscure dark 

 crossbars. Fins plain, yellowish in male, speckled at base only. Length 

 2| inches. Eastern North Carolina; abundant in spring brooks, not 

 descending to salt- water; a pretty little fish, representing a transition 

 from Fundulu* to Zygonectes. (Named for Richard Rathbun, Chief of the 

 Division of Scientific Inquiry of the United States Fish Commission.) 

 riiiiiliilus rathbuni, JORDAN & MEEK, Proc. U. S. Nat. Mus., 1888, 356, Reedy Fork, Alle- 

 mance Creek, Buffalo Creek, and other tributaries of the Cape Fear River, 

 about Greensboro, North Carolina. (Type, No. 39860. Coll. Jordan, Jenkins &

947. FUNDULUS ALBOLINEATUS, Gilbert. 



Head 3i to 3f ; depth 4 to 4i ; least depth of caudal peduncle equals 

 snout and eye. Scales 42; D. 10 or 11; A. 10 or 11; B. 5. Teeth 

 sharp, wide set, in a broad band on premaxillaries, a narrow band on 

 mandible. Snout i length of head. Width of interorbital space 2 to 2i 

 in head. Dorsal and anal opposite, or the dorsal slightly in advance, 

 their bases equal and short, equaling length of snout and half eye; in 

 males both fins become elevated, the longest anal ray equaling f head, 

 and the anal rays become covered with prickles ; in males the pectorals 



* This species and the four which follow seem to be entirely intermediate between the typi- 

 cal species of Fundulus and the species called Zygonectes. Their presence makes it apparently 

 impossible to maintain Zygonectes as a distinct genus, notwithstanding the great difference 

 between such species as F. dispar and F. majalis.
