thp: cyprinodonts. 31 



Gunther says the males have nine or ten silvery cross bars, each about as 

 broad as a scale, black anterior dorsal rays, and a blackish band across the 

 hinder half of the caudal ; and that the females are silvery on the side with 

 more or less numerous narrow black vertical stripes, which do not extend on 

 to the back or to the belly ; while m the young the cross bars and stripes are 

 as frequently present as absent.

Shape similar to that of L. cahritana. Body compressed, depth about 

 equal to length of head, which is two sevenths of the length to the caudal 

 base. Head as wide as deep, little less than one fourth of the total length ; 

 crown flat. Snout short, half as long as the eye, blunt ; chin steep, nearly 

 vertical. Mouth moderate, opening obliquely upward ; lower jaws longer ; 

 upper short, proti-actile. Eye large, twice the snout, once the forehead, two 

 fifths of the head. Dorsal origin slightly in advance of the middle of the 

 total length, about midway from occiput to base of caudal. Origin of anal 

 below third or fourth ray of dorsal. Ventrals small, six-rayed. Pectorals 

 reaching a vertical from the bases of the ventrals. Outer margins of dorsal, 

 anal and caudal convex. Intestine about one and one half times the total 

 length. 



Light brownish or olivaceous ; belly and lower half of head silvery. Darker 

 specimens with a silvery band faintly indicated along the lateral line. Females 

 with three or four longitudinal series of small spots of brown along the sides. 

 The hindmost spot, on the middle of the base of the caudal, is commonly 

 black. On the caudal, near the spot, there is most often a faint transverse 

 band and the tip of the fin is somewhat dark. The fins are dotted or uni- 

 form. The male has numerous, 12-16, narrow bands across the sides, and 

 one to three brownish to black ones across the caudal. 



The specimens described are from Barcelona, Spain.
