NO. 20 A NEW GOBY GINSBURG 3 



streaks at base, and distally in the form of elliptical peripheries havinf^ 

 whitish, irregularly shaded centers; second dorsal colored somewhat 

 like the general color pattern as described for the first dorsal ; caudal 

 with lower half nearly uniformly dusky, upper half with the pigment 

 concentrated in elliptical peripheries having variously shaded centers, 

 more marked than on the dorsals, produced part of fin and posterior 

 margin blackish ; anal and ventral very dark, nearly black ; pectoral 

 dusk-y ; upper lip dusky, but the pigment not markedly more intense 

 than on rest of snout, no distinct black band. All fins, except the pec- 

 toral, more or less washed and daubed with a whitish color. 



Comparison. — The specimen described was compared with speci- 

 mens of all the species of Bolhwinia now known, except (Gobius) 

 Bollmanm eigefimanni Garman. No specimens of the latter are availa- 

 ble for comparison, and I had to rely solely on the original account. 

 As compared with the four species of Bollniania from the eastern 

 Pacific,'' litura differs chiefly in having fewer rays in the vertical fins. 

 As compared with its two known congeners occurring in the same 

 faunal region with it, litiira differs from B. boqueronensis Evermann 

 and Marsh ^ in having a much more elevated dorsal ; and from 

 B. eigenmanni (Garman)^ in having a longer ventral and caudal and 

 in lacking a black band on the upper lip. The presence of a median 

 row of blotches is unique for a species of BoUmania. The only other 

 species of this genus which apparently approach litura in this respect 

 are B. macropoma Gilbert and B. chlamydes Jordan from the Pacific, 

 which were originally described as having the sides with vertical dusky 

 bars. The specimens of the latter two species which I examined are 

 now faded, and the color cannot be compared. 



Holotype. — U.S.N.M. no. 93797. A male, Caroline station 59. 

 Samana Bay, Dominican Republic, trawled in 18 tO' 19 fathoms, on a 

 mud bottom. The type is the only specimen now known.
