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. nov. (29247.) 



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

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

 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^ in head. 

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

 Distance from base of caudal to front of dorsal 34 in total length. Cau- 

 dal truncate. Head 3 in length ; depth 5J. D. C ; 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 ; fins otherwise 

 nearlj^ 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 1^ inches long. 



25. Gobiesox erythrops, sp. nov. (29248. ) 



Head scarcely longer than broad, proportionately very broad and 

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

 aud 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, 2f in body. Pectoral about one-third length of head. Dis- 

 tance from fiont 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 up])er border blackish ; 

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



But two specimens, 1^ 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 upper jaw narrow, blunt, little compressed, 

 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 length of the head and about half greater 

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