Coloration : Back and sides dark steel blue, lighter towards the belly; 

 chin, throat, and belly white, the body with about twelve nearly ver- 

 tical blackish cross bands, about as wide as the eye. The bands reach- 

 ing the belly, sides of the face, under and in front of the eye silvery, 

 but interrupted by a dark streak running from the maxillary to the 

 angle of the opercle. An inky blotch on the margin of the opercle 

 above the angle. Axilla black, the black extending somewhat below 

 the base of the pectoral. Dorsal and anal dusky. Upper side of ven- 

 tral dusky, lower side pale, but dusky on the webs towards the tips. 



A very beautiful fish, apparently not common at Guaymas; two 

 specimens were obtained, respectively 195 and 213"' m in length. 



8. Pseudojulis venustus, sp. nov. (Type, No. 39631, U. S. N. M.) 



Head with flap 3.3 in length of body to base of caudal, without flap, 

 4; depth of head, 5.3 ; width, 9 iu length of body ; depth of body, 3.6; 

 width, 10 in the length ; dorsal fin, IX — 12 ; anal fin, III — 12 ; scales, 

 3-20-8 ; scales before the dorsal about 11. Body elongate, compressed, 

 back more elevated iu the older males ; scales large, smaller on the 

 breast; head, cheeks, opercle, and preopercle naked, preopercle entire. 

 Teeth large, the four front ones in each jaw stronger. The posterior 

 canines in four specimens present the following characteristics : In No. 

 1, small one present on the right side, absent on the left; in No. 2, barely 

 evident on the right side, absent on the left ; in No. 3, absent on the 

 right, barely evident on the left; in No. 4, not evidently present on either 

 side. Dorsal spines pungent, anal spines graduated, the first very 

 weak, almost rudimentary. Gill-rakers on lower limb of the anterior 

 arch about 9, slender, less than 0.5 the diameter of the pupil, on suc- 

 ceeding arches still shorter, almost rudimentary on the fourth arch. 

 Gill membranes joined to the isthmus. Color in life : Dorsal and anal 

 fins rose red, with white edges; caudal orange; general color of the body 

 olivaceous ; a row of black spots on the back at the base of the dorsal, 

 other spots along the lateral line. In the larger specimens, the males, 

 there is a dark blue cross bar as wide as the eye on the body, at a dis- 

 tance of twice the diameter of the eye behind the pectoral, extending 

 from the belly nearly to the lateral line. Teeth not evidently in two 

 series. The front teeth canine-like. Snout 2.75 iu length of the head 

 without flap. Eye small, 5.75 in length of head without flap. 



Pectorals 6 in the body length, extending to the tip of the ventrals. 

 The ventrals are 7.5 in the length of the body, their origin being on a 

 vertical passing through the posterior edge of the axilla. The lateral 

 line drops abruptly a distance of three scales at a point two scales iu 

 front of the last dorsal ray. 



This species is intermediate between Platyglossiis semicinctus (Ayres) 

 and P. californicus Giinther ( = P. modestus Grd.), the color much like 

 the former, the form intermediated. 



A very beautifully colored and graceful fish, not common at Guay- 

 mas, at which place we obtained four specimens.
