Very abundant in the rocky tide-pools around Mazatlan, hiding under 

 the numerous sea-urchins. About 30 specimens were collected, the 

 largest nearly 3 inches long. 



24. Gobiesox eos, sp. uov. (29247.) 



Body comparatively short, stout, and narrow, the head rather broad;> 

 but, as well as the body, much less depressed than in G. erythraps ; 

 the width of the head less than its length, contained 3| times in 

 body; incisors serrate or tricuspid, the teeth as in G. zebra. Eye 

 moderate, about 1^ in interorbital space, which is about 3.J in head. 

 Pectoral about one-half length of head. Ventral disk shorter than head. 

 Distance from base of caudal to front of dorsal 3| in total length. Cau- 

 dal truncate. Head 3 in length ; depth 5^. D. 6; A. 6. Bright rosy 

 red, sometimes made dusky above with black points ; back with from 

 one to three faint dark bars ; three dark lines downwards and backwards 

 from orbit, and usually one or two more on the opercle ; caudal usually 

 with a reddish bar at base and a dusky one towards tip; tins otherwise 

 nearly plain. 



Very abundant in the rock -pools, where it is nearly always found, in 

 company with G. zebra, hiding under the sea-urchins. The largest ex- 

 amples seen are about IJ inches long. 



25. Gobiesox erythrops, sp. nov. (^9248. ) 



Head scarcely longer than broad, proportionately very broad and 

 depressed, its breadth three times in total. Incisors in both jaws entire 

 and rather broad, the lateral teeth, as usual, pointed ; no canines. Eyes 

 very large, considerably wider than the narrow interorbital area, 3^ in 

 head ; interorbital area nearly 5 in head. Ventral disk a little longer 

 than head, 2§ in body. Pectoral about one-third length of head. Dis- 

 tance from front of dorsal to caudal, 3f in body. Caudal truncate with 

 rounded edges. 



Head 2^ ; depth 6. D. 6 ; A. 5. 



Light olivaceous ; body with three or four bars of cherry red ; head 

 marbled with red ; eyes intensely cherry red, their upper border blackish j 

 fins pale, the upper mottled with reddish ; caudal barred with red. 



Biittwo specimens, IJ inches long, taken in a rock -pool; evidently rare. 

 A specimen of this species from the Tres Marias Islands, is in the col- 

 lection at Woodward's Gardens, San Francisco. 



26. Gobiesox adustus, sp. nov. (29249.) 



Head and body broad and flat, much depressed; width of head 

 nearly equal to its length, 3§in body. Incisors in middle of lower jaw 

 broad, entire; those in ujjper jaw narrow, blunt, little comj)ressed, 

 entire, shorter than the lateral teeth ; behind these two or three series 

 of smaller teeth. Eyes rather large, separated by a broad interorbital 

 space, which is one-third the leugth of the head and about half greater 

 than diameter of eye. Opercular spine sharp. Pectoral short, about half
