northward, in deeper water southward. The shining spots along 

 the sides and ventral region of this fish have suggested brass but- 

 tons, and given to it its common name, midshipman. It is also 

 called singing-fish, on account of the loud hunnning noise it makes 

 when disturbed. 



Family GOBIESOCID^. 



210. Gobiesox papillifer Gilbert. 

 (Jordan and Evermann, 1898, III, p. 2330.) 



One specimen 2 inches long from San Pedro. It has hitherto 

 been known only from IMagdalena Bay, Lower California. It 

 shows the following variations from the description of the type 

 (Gilbert, 1890, p. 96). The anal has 10 rays (not 9) ; the eye is 

 % of interorbital width (not i/o). The bars on the vertical fins 

 are very indistinct ; the white bar said to follow the black bar at 

 base of fins can not be distinguished from the dusky area follow- 

 ing; the white margin is evident. 



211. Rimicola eigenmanni (Gilbert). 

 (Jordan and Evermann, 1898, III, p. 2339.) 



Known only from a single specimen, the type, taken at Point 

 Loma and from specimens taken at San Cristobal Bay (Smith, 

 1881, p. 553, under the name of Gobiesox rhessodon). 



212. Arbaciosa rhessodon (Rosa Smith). 

 (Jordan and Evermann, 1898, III, p. 2340.) 



Specimens taken in abundance in tide pools on the ocean side 

 of Point Loma, at La Jolla, and San Pedro. 



A cotype in the collections of Stanford University is identical 

 with our specimens, but differs from the original description 

 (Rosa Smith, 1881, p. 140) in having the eye "^^oo of the total 

 length to base of caudal, not ^luo- It differs from the description 

 by Jordan and Evermann in having the head contained 2% times 

 in body, not 3i/4 times; the eye 6 times in head, not 4I/2 times. 



It is found in abundance in rock pools southward to San Bar- 

 tolome Bav, Lower California.
