i 9 4i CATALOGUE OF FISHES OF TORTUGAS 265 



sexual characters, equally evident in mature males from Florida and from 

 Bonaire. In specimens 22 mm. and upward in length these characters differentiate 

 the sexes, and at the small size of 12 to 13 mm. the males already are distin- 

 guishable by their more prominent urogenital papilla, and by the larger and 

 broader ocular cirri. 



Peculiarities that distinguish the types 0/ Stathmonotus tekja (22 and 23 mm. 

 long), which I have examined, are artifacts. The fin formulas in both specimens 

 are D. XL; A. 23; not all the characteristic cirri nor all the scales are missing; 

 and the characteristic light blaze runs backward from behind eye. Examination 

 of type material of Histioclinus veliger shows that in several respects the original 

 description is incomplete or erroneous. The dorsal fin supports are spines, not 

 articulated rays, and the scales in the figure are shown as very much smaller than 

 they actually are. They are reduced anteriorly, and wanting on breast and axil of 

 pectoral. The small teeth, present in an inner series near the symphysis in the 

 upper jaw and on the vomer, escaped detection. Ten specimens from the type 

 locality have D. XLI to XLIV; A. 11,24 to 2 ^ ana * 10 Tortugas specimens have 

 D. XL to XLIV; A. II,2 4 or 25; P. 8; V. 2. 



The number of eggs produced by a female is small, and they do not all mature 

 together. W. H. L. 



The collection contains 6 specimens, 20 to 28 mm. long. The following pro- 

 portions and enumerations are based on a specimen 23 mm. long to base of 

 caudal, and on a paratype 19 mm. to base of caudal: Head 4.6, 4.75; depth 7.5, 



6.5. Eye in head 5.0, 4.0; snout 4.5, 5.0; pectoral 4.2, 4.6. D. XLI, XLIV; A. 11,24, 

 11,26.

Stathmonotus hemphillii Bean 



Dr. Longley stated in his notes that he took 2 specimens in 5 to 6 fathoms. His 

 collection contains these 2 specimens, 30 and 35 mm. long, and a third, 42 mm. 

 long, without data, which is black in preservative and seems to have been dry. 



Although the color of the Tortugas specimens does not fit the description of 

 Stathmonotus hemphillii entirely, the fin-ray counts and proportions seem to be 

 about right. On comparison of the specimens with the types (U. S. Nat. Mus. no. 

 37193), no differences in structure were noticed. The color seems to be variable. 



The following proportions and enumerations are based on the 2 smaller speci- 

 mens in the collection: Head 6.2, 6.5; depth 10.6, 12. Eye in head 4.9, 5.0; snout 



5.6, 6.1; maxillary 3.0, 3.5; pectoral 5.6, 6.1. D. L, LI (LI in each of 2 type speci- 

 mens) ; A. 11,28, 11,29 (11,26 and 11,27 in types). 



Dr. Longley has the following on color : "The coloration is evidently variable. 



One of the 2 specimens has much more fully developed than the type the white 



spots on the anal fin, matching those in the dorsal series. The other lacks the 



anterior two-thirds of the white markings which suggested the generic name." 



Dr. Longley stated further, "The fish's motion is eel-like."
