1941 CATALOGUE OF FISHES OF TORTUGAS IO y 



Its fin formulas are: D. X,i2l4; A. 111,7%; P. 16. Branchiostegal rays 7. Scales 

 4-46-12, with five oblique rows on the cheek. Proportional measurements of a 

 representative specimen are: Total length 118 mm.; standard length 94 mm.; 

 depth 2.8; head 3.1. Eye in head 3.0; preorbital width 7.5; interorbital 10. The 

 type of P. atrobranchus, as measured by me, has a total length of 124 mm.; 

 standard length 95 mm.; depth 2.7; head 3.05. Eye in head 3.25; interorbital 7.7. 



The Tortugas fish is very lightly pigmented; merely dusky above, paler below; 

 trunk to vertical of anal origin shimmering with metallic reflections; black 

 lining of operculum, visible through opercle, giving the appearance of a distinct 

 black opercular spot. The Brazilian specimen (type) is much darker and ob- 

 scurely banded, and has a corresponding black opercular spot of like origin.

Serranus Cuvier, 1817 



Dr. Longley described two new species from Tortugas under this generic 

 name. One of these is listed herein as Prionodes notospilus in accordance with 

 the manuscript prepared by him, where it undoubtedly belongs if Prionodes de- 

 serves recognition. It is different, however, with his Serranus tortugarum, which 

 has the margin of the sub- and interopercle serrate, and the gill rakers long and 

 numerous. A second species, represented by a single specimen, agrees in these 

 respects with S. tortugarum. This species I have named Serranus beta. As these 

 species are of uncertain generic affinities, it seems desirable to leave them in 

 Serranus until further study is made, and the genera become more accurately 

 defined. S. F. H.

Dules subligarius (Cope) 



Only one specimen, 31 mm. long, caught on "Emblemaria grounds," seems to 

 be listed by Dr. Longley. Though this specimen was not found, the collection 

 contains one 45 mm. long. The following counts were made: Branchiostegals 6; 

 D. X,i3; A. 111,7; scales 6-42-14. 



Concerning the color, Dr. Longley noted: Head before the scaled area with 

 brown stripes on a gray ground, a pattern common in the young; a spot of brown 

 on conjunctiva above; the dark line through pupil bordered above and below
