San Clemente Island. The measurement of the spinous dorsal in the 

 table of Snodgrass and Heller is of the second ray, the first and longest 

 ray being broken ; the pectoral fin is also broken, the fin being nmch 

 longer than indicated. 



Scales with a row of apical spines; no scales on head, belly, nor 

 along base of spinous dorsal. Cross bars half as wide as interspaces 

 in the largest specimens, but relatively much wider in those as small 

 as the type; the bars in alcoholic specimens are olive brown, with 

 darker streaks along each border and near the center. Last soft ray 

 of dorsal and anal longest. In the adult, but not in the young, the 

 first dorsal spine is filamentous. Teeth in a wide mandibular baud; 

 and in a narrow maxillary band, the outer series of which is enlarged. 

 The teeth of the lower jaw are not in 2 series, as stated by Snodgrass 

 and Heller.

Gillichthys mirabilis Cooper 



This curious mud-burrowing goby was found abundantly in bays 

 and sloughs at Ventura, Playa del Rey, San Pedro, Anaheim Bay, 

 Mission Bay, and in sloughs at the mouth of Tia Juana River, near the 

 Mexican border. 



Clevelandia ios (Jordan and Gilbert) 

 This little goby, together with the related species, Quietula ij-caiida 

 and Ilypnus gilberti, is common about the sloughs, especially in the 

 small pools left on the mud flats by the retreating tide. They have
