FAMILY CALLIONYMIDAE — SCHULTZ 405 



Foetorepus Whitley, Australian Zool., vol. 6, p. 323, 1931 (type species, C. 

 calauropomus Richardson) . 



As a result of my work in connection with identifying the Marshall 

 Islands specimens, I find that Callionymus splendidus Herre (Philippine 

 Journ. Sci., vol. 32, p. 416, pi. 2, 1927) has as a synonym Synchiropus 

 leopoldi Giltay 1933 (Banda). C. zaspilus Herre (Copeia, No. 1, 

 p. 24, 1931), from the Philippines, with 24 pectoral rays, may be a 

 species distinct from splendidus, with 29 to 31 rays. 



To C. ocellatus Pallas 1774, I refer as synonyms: Synchiropus shoe 

 Okada and Ikeda 1937, based on an examination of one specimen 

 from Okinawa that agrees with their description; S. lili Jordan and 

 Scale 1906, based on a comparison of the holotype USNM 51762, 

 from Samoa, with Philippine specimens of S. ocellatus; Callionymus 

 rubrovinctus Gilbert (Bull. U. S. Fish Comm., vol. 23, 1903 pt. 2, 

 p. 650, fig. 252, 1905), doubtfully referred to the synonymy of C. 

 ocellatus, based on an examination of the holotype, USNM 51580. 



Synchiropus lineolatus (Cuvier and Valenciennes) probably has as 

 synonyms C. lateralis Richardson 1844 and S. ijimae Jordan and 

 Thompson 1914. In this species the orbit may have a small orbital 

 tentacle, if figures are correct, although that character is not 

 mentioned in the descriptions. 



The following additional species from the tropical Indo-Pacific 

 region belong in the genus Synchiropus: C. calauropomus Richardson 

 1894; S. sechellensis Regan 1908; S. pallidus Fowler 1941, USNM 

 99437; S. grinnelli Fowler 1941, USNM 99436; S. delandi Fowler 

 1941, USNM 99524; C. hicornis Norman 1939; S. ornatus Fowler 

 1931; and C. microps Giinther 1877. Callionymus altivelis Temminck 

 and Schlegel (Fauna Japonica, pt. 4, p. 155, pi. 79, fig. 1, 1845), from 

 Japan, must be referred to Synchiropus, along with the homonym 

 S. altivelis Regan (Trans. Linn. Soc. London, vol. 12, p. 249, pi. 30, 

 fig. 1, 1908, Seychelles) =/S'. altivelus Norman (in John Murry Expedi- 

 tion, 1933-34, Scientific Reports, vol. 7, No. 1, Fishes, p. 75, fig. 27, 

 1939, Gulf of Aden), for which has been proposed the substitute 

 name S. normani Schultz and Woods 1949. To this genus C. picturatus 

 Peters 1876 also is referred by de Beaufort. 



A few other Pacific species, not studied in sufficient detail to allocate 

 them with certainty generically, probably also belong in this genus. 



The following key distinguishes the species of the Northern Marshall 

 Islands and Marianas Islands: 



la. Pectoral rays 17 to 22, 



2a. Pectoral rays 17 or 18; dorsal 9; anal 8; no ocelli in spiny dorsal fin; a 

 tiny black dot at lower part of pectoral base and another on branch- 

 iostegals of males; females mostly unpigmented; usually 4 or 5 spiny 

 points on preopercular spine S. laddi, new species
