FAMILY SCHINDLERIIDAE — SCHULTZ 397 



Color in alcohol. — Light brownish. 



Color when alive. — Transparent. 



Remarks. — This strange family of pelagic fishes is known from the 

 tropical Pacific through the following publications: 



Schindler (Anz. Akad. Wiss. Wien, No. 9, p. 79, 1930, Ihid, No. 1, 

 p. 2, 1931; Bernice P. Bishop Mus. Bull. 97, pp. 1-28, pis. 1-9, 1932; 

 Sitzb. Akad. Wiss. Wien, vol. 143, p. 265, 1934); Giltay (Bull. Mus. 

 Hist. Nat. Belgique, vol. 10, No. 13, pp. 1-10, figs. 1-4, 1934); and 

 Bruun (Dana Report, vol. 4, No. 21, pp. 1-12, figs. 1-8, 1940). 



S. jpieischmanni (Schindler) is known only from the Hawaiian Is- 

 lands, whereas S. praematurus has been found in the Hawaiian Islands; 

 Manokwari, New Guinea; Papeete Harbor, Tahiti; Apia Harbor, 

 Samoa; Tasman Sea, off Sydney, and Grafton, Australia; and my 

 specimen from Bikini lagoon. Undoubtedly this pelagic species will 

 be found widely distributed in the tropical Pacific. Most of the ma- 

 terial so far collected has been taken with a dip net at night, as Schind- 

 leria was attracted to a fight. 



Suborder Callionymina 



Family CALLIONYMIDAE 



By Leonard P. Schultz 



Schultz and Woods (Joum. Washington Acad. Sci., vol. 38, No. 

 12, p. 419, 1948) defined relationships within this family in their key 

 to the genera of Callionymidae. Unfortunately, the usefulness of 

 their key was impaired when, through a printer's error, couplet 56, 

 which should have followed 76, was transposed to follow 5a. Also, in 

 couplet 26 and footnote 9 the generic name Dactylopus is misspelled. 



Since that time de Beaufort has published a valuable account 

 (Fishes ot the Indo-Australian Archipelago, vol. 9, pp. 50-81, 1951), 

 giving a key to the genera which differs considerably from the one 

 published by Schultz and Woods. 



The species referred to this family, numerous and too frequently 

 not adequately described, are in need of revision. Much of the 

 confusion results from the sexual dimorphism and sexual dichromatism 

 so characteristic of the members of this family. Adult males may 

 have greatly elongated fin rays when compared with the females; 

 thus, females and males are described as distinct species. 



Ochiai, Aroga, and Nakajima (Publ. Seto Mar. Biol. Lab., vol. 5, 

 No. 1, pp. 96-132, figs. 1-18, 1955) revised the species from Japan 

 referable to Callionymus. They recognize 16 species.
