2^4 PAPERS FROM TORTUGAS LABORATORY vol. xxxiv 



ocular cirri are somewhat stout, usually palmate, and about 6- to 8-parted; nuchal 

 combs much simpler than in related species, usually showing no more than 5 

 divisions; scales larger, usually 3 or 4-44 or 45-14. Even the fin formulas tend to 

 set it apart, for in every instance the count in some respect exceeds the limit 

 attained by 61 specimens of bucciferus, the species nearest it in this respect. 

 The largest specimen observed was only 70 mm. in length. W. H. L. 



The collection contains 3 specimens, 38, 39, and 58 mm. long. The fin-ray and 

 scale counts agree with those given by Dr. Longley. The following proportions 

 are based on the smallest and largest specimens in the collection: Head 3.3, 3.3; 

 depth 4.3, 4.5. Eye in head 2.7, 2.9; snout 4.5, 4.75; maxillary 2.1, 2.3; pectoral 

 1.0, 1.1.

This species is not known from Tortugas. 



In Vienna there is a specimen, identified by Steindachner as "Clinus nuchi- 

 pinnis C. & V.," which on its label has the notation "Labrisomus bucciferus Poey, 

 Typus." That this fish is the type seems almost certain, as its length is 55 mm., as 

 Poey stated. Its pectoral rays are 13 on one side and 12 on the other, the latter 

 being Poey's count, though that number does not occur again in 60 other speci- 

 mens examined. The dorsal fin has XX, 11 rays, as Poey stated, and the anal 

 11,20, which is a ray more than he gave. 



From the data in table 9 the mode in respect to fin formulas is definitely deter- 

 minable and the range of variation approximately so. It will be noticed that the 

 range of variation in L. bucciferus overlaps that in several related species, from 

 which on other grounds it is readily distinguished. 



The color pattern and general appearance are well represented in Nichols' 

 figure of L. heilneri (see reference above), in which attention may be drawn to 

 broken bands on the body, banding on the anal fin, and a faint dark line down 

 and back from the eye paralleling the preorbital border. Below this line the cheek 

 is usually distinctly dark. Above it the postorbital region is abruptly paler and 

 sometimes dark-spotted.
