i 9 4i CATALOGUE OF FISHES OF TORTUGAS 269 



eroded coral, and the other still held cupped beneath it by the hinge ligament, 

 3 specimens were taken during the course of about a week. 



In 6 Tortugas specimens the fin formulas are D. XII, 12 or 13; A. 11,14 or J 5> 

 V. 1,4. This accords with the original description, except for the ventral, which 

 in the type is said to have only 3 rays; this was found to be correct for one fin, 

 though the usual number of 4 is present in the other. 



The sexes may be distinguished readily by their ocular cirri and teeth, and 

 infallibly by their external genitalia. In either sex the cirrus is superior, trans- 

 versely flattened, digitate, 3 to 5 times parted. In the female the elements are 

 approximately equal and in length considerably less than half the eye. In the 

 male one element is much longer than the others, exceeds the eye's diameter, and 

 extends almost or quite to dorsal origin. Both have normally an enlarged, re- 

 mote, recurved canine on either side in each jaw, which are much larger in the 

 male. The type, a female, though correctly described, is abnormal in lacking 

 lower posterior canines. The external genitalia in the male consist of rounded, 

 rugose fleshy knobs on the anal spines, whereas the female has an expanded tri- 

 angular fleshy shield in which the 1st anal spine is buried so deeply that only its 

 tip shows as a slight papilla. See plate 31, figure 1. 



The female in particular is changeable in coloration. In a white dish the 

 median third only of her six broad, dark bars remains deeply brown. The upper 

 and lower two-thirds become grayish olive with a finely reticulated pattern of 

 pale blue about brassy dots, net and spots being most distinct on the head. The 

 bars are separated by light saddles. By narrow lines these saddles connect with a 

 similar series of ventral white marks. Occasionally the entire side of the body 

 below the darkest lateral blotches turns nearly white. The male seems always 

 darker than the female. Its first two light bands almost disappear in a black dish. 

 On the Orbicellas the colors of both sexes are most vivid. Their dark and light 

 bars contrast, and the olive on head and nape is enriched by yellow, simulating 

 the hues of living and dead coral and thick shadows. 



On June 13 the ovaries of a large female contained eggs so nearly mature as 

 to indicate an early breeding season. W. H. L.
