2. TJPSILONPHORUS GUTTATUS (Abbott). 



(Astroscopus anoplus Bean, Proc. U. S. Nat. Mus., 1879, 60.) 



3. Upsilonphorus y-gr^cum (Cuv. & Val.). 



Aslroscopus II gnicnm Beau., Proc. U. S. Nat. Mus., 1879, 61. 



Astroscopns anoplus Jor. & Gilb., Proc. U. S. Nat. Mus., 1882, 289 (Peusacola, 



young). 

 Astroscopns y-grcecum Jor. & Gilb., Proc. U. S. Nat. Mus., 1882, 610 (Charleston, 



adult). 



The comparison between A. anoplns and A. ygrcecum by Jordan &, 

 Gilbert, 1. c, 289, is vahieless, as the specimens examined were respect- 

 ively the yonng and the adult of y-grcvcum. According to Dr. Beau, 

 Astroscopns guttatuSj of which he has examined both young and old, is 

 distinct from ygrcecum. The adoption of the name anoplus instead of 

 guttatus is, as we have seen, improper. 



Both TJ psilonpliorus and Astroscopns are defined with perfect correct- 

 ness by Gill (Proc. Acad. Nat. Sci. Phila., 18G1, 113), except for the 

 statement that in the latter the body is naked. 



LEPTOSCOPID^. 



144. Dactyloscopus tridigitatus Gill. 



Three specimens taken with the seine in the surf, on sandy bottom. 



Pale sand color above, the lower parts whitish ; above 12 narrow 

 cross-bands of whitish on the back, not extending down far on the 

 sides ; head mottled above ; fins all pale. 



The pseudobrauchiae in this species are small, but evident. There is, 

 therefore, no real difference between Dactylagnus, which has psuedo- 

 branchise, and Bactyloscopus^ of which this is the typical species, and in 

 which they were said to be wanting. 



GOBIIDiE. 



145. Gobius soporator Cuv. «& Val. Bock-fish. 



{Gobius mapo Poey.) 



Yery abundant everywhere in the tide-pools and shallow waters. 



146. Gobius stigmaturus Goode & Beau. 



Two specimens taken with the seine in a shallow bay. 



Very pale olive, everywhere freckled and spotty; lower part of sides 

 silvery, crossed by faint and narrow cross streaks of light brown ; sides 

 with about five faint dark blotches ; a dark blotch below eye and one 

 on opercle ; a round black spot at base of caudal ; bars on vertical fins 

 light olive. 



Numerous other specimens are less freckled in coloration, and have a 

 more diffuse caudal spot as well as a vague dark spot at the shoulder. 

 The dusky marks on the sides are larger. I cannot find any other dif- 

 ferences, and refer all of them to G. stigmaturus. The relations of G. 

 'boleosoma. G. stigmaturus^ and G. encceomus are certainly very intimate.
