1941 CATALOGUE OF FISHES OF TORTUGAS 231 



t, dorsal spines in the male elongated, the 3d one extending much beyond the 

 others, sometimes reaching base of 6th ray of second dorsal or beyond; longest 

 spine barely reaching origin of second dorsal in largest female. 



This species, if on clear white bottom, is nearly as light as the bottom. It is 

 finely mottled with gray and has a few distinct dark brown or black spots as fol- 

 lows: a narrow line from below eye to angle of mouth; dark spots on iris below 

 and above pupil; a small dark spot under opercle, and a series of six or seven 

 linear dashes, shorter than the interspaces, extending from pectoral axil to middle 

 of caudal base; several narrow dark lines extending downward and backward 

 on dorsal fins; caudal fin barred similarly. 



The male is mature at a length of 25 mm., or possibly less, and the female at 

 little over 30 mm. Breeding was under way on August 11, 1927. Eggs were laid 

 and fertilized then in a battery jar on the laboratory table. The eggs, perhaps 12 

 hours after fertilization, were spherical and 3.7 to 3.9 mm. in diameter. Some, 

 but by no means all, bore a very slight tuft of adhesive filaments which varied in 

 thickness from 0.15 to 0.30 mm. The eggs do not adhere to glass, but will stick to 

 fragments of algae or to one another by the entangling or adhesion of holdfasts. 

 The embryos are colorless, the yolk opaque and grayish. The yolk sacs of most 

 of the advanced embryos contained a single oil globule about 0.11 mm. in diam- 

 eter, but in earlier stages of development they had any number up to a dozen or 

 so, of which the largest measured about 0.45 mm. W. H. L. 



The collection contains 2 small specimens, in addition to 7 others, not in good 

 condition, evidently picked up at the bird rookery, as shown by the pieces of 

 broken mollusk shells adhering to them. 



Brazil, West Indies, and Florida. S. F. H. 



Bollmannia boqueronensis Evermann and Marsh 



In waste from the Bird Key and Long Key tern rookeries were 3 specimens, 

 65 to 75 mm. long, in very good condition. Two other specimens were removed 

 from the stomach of a Trachinocephalus myops, caught in 10 fathoms east o£ 

 Loggerhead Key. 



Tortugas specimens have D. VII-I,i2}4; A. 1, 12 to I2 1 /,- The dorsal spines are 

 a little higher in the male, the 5th, in the male, when depressed extending to base 

 of 4th ray of second dorsal; in the female, to about the 2d; soft fin extending to 

 base of caudal in both sexes; scales in linear series 27 or 28; horizontal rows 

 eight, counting up and forward from the vent; cheek and opercle scaly; about 

 nine rows of scales before dorsal. 



Ground color very light; head striped diffusely with a median and two other 

 dusky lines on side, the upper of the two just above eye, continuing on trunk, the 

 lower, as a series of four or five spots, extending to base of the long, pointed 

 caudal. Through the transparent flesh one may see an internal pattern, not made 

 out in detail. The dorsal fins are streaked with narrow parallel lines of sulphur 

 yellow, of which the course of the basal two is modified slightly to form a semi- 

 ocellus on the 3 webs behind the 5th spine in the male, and less conspicuously 

 behind the 6th in the female. W. H. L.
