88 PAPERS FROM TORTUGAS LABORATORY vol. xxxiv 



tive Zoology (no. 9745) a female, 88 mm. long, with a slightly frayed caudal, 

 which is marked "Poey's original." In the U. S. National Museum (no. 8804) 

 are 2 specimens in poor condition but clearly referable to this species. They came 

 from Poey under the number 436, which is the number assigned to maculatus in 

 his private collection and in all his publications relating to it. There can be no 

 doubt, then, as to the identity of the Tortugas specimens with Apogon maculatus. 



W. H. L. 



The collection contains 28 specimens, ranging in length from 30 to 102 mm. 

 The dark or dusky blotch below the opercular spine, another more definite one 

 under the soft dorsal, and a dark saddle on the peduncle at base of caudal, which 

 are larger (especially the two posterior ones) than in A. pseudomaculatus, serve 

 as recognition marks. The absence of black on the lobes of the second dorsal and 

 the anal also aids in separating this species from A. pseudomaculatus, and judg- 

 ing from the specimens preserved, A. maculatus attains a larger size.

Apogon binotatus (Poey) 



Jordan and Evermann (Bull. U. S. Nat. Mus., No. 47, pt. 1, 1896, p. 1109) have 

 adequately summarized the original description, except that the term "sub- 

 bifurcada," applied to the form of the caudal, is rendered "lunate," which is in- 

 accurate. Poey mentioned no point, save color, in which this species differs from 

 Apogon pigmentarius. The two, however, as appears from examination of the 

 type (no. 9750) and other specimens (nos. 9747, 9755) in the Museum of Com- 

 parative Zoology, are sharply distinct. The 2d dorsal spine in A. binotatus is 

 much stouter than the 3d, and usually extends as far as its tip; the posterior 

 margin of the preopercle is more strongly serrate; the scales on the caudal 

 peduncle are in two rows above and two below the lateral line, in addition to the 

 median dorsal and ventral series. 



Three specimens were found in waste of the tern rookery. The range of this 

 species includes the shallow water of Bird Key flats. Specimens were occasionally 

 taken by breaking up clumps of the fragile, branching coral, Pontes pontes, 

 lifted bodily from the water, and with the diving hood others were seen lurking 

 in the shelter of massive corals in the 15-foot holes near by. 



Ground color variable, sometimes changing in a moment from vermilion to 

 flesh color; pale phases shown at night, or amid light-colored surroundings; dark 

 markings never disappearing wholly. The narrowness of the bars crossing body 

 between posterior ends of bases of dorsal and anal, and at base of caudal, is dis- 

 tinctive. There are no white lines on the eye, as in A. maculatus; and the lobes of 

 the vertical fins are not black-tipped, as in A. pseudomaculatus. W. H. L.
