372 BULLETIN OF THE BUREAU OF FISHERIES. 



A series of six specimens, mostly from Pago Pago, were very aberrant. Life colors of one of these, rich 

 orange-brown, paler bright orange on snout, light orange on belly; everywhere round pale blue spots 

 edged with darker blue, these largest on side of belly, smaller on side of tail, deepest on middle of 

 back; a faint blue median ventral streak; blue cross-streaks on snout and as far back as behind eye, 7 

 in all, the posterior darker edged; spots confluent into a streak on front of back; a black spot below 

 dorsal, with 4 blue spots and streaks about it, a curved blue streak above it on fin; back of tail with 

 spots only; tail orange, with blue spots in vertical rows, and a dark blue edge; fins otherwise colorless 

 orange, with blue spots about vent. 



In alcohol these specimens have the spots larger and sparser, and the spots below the eye and on 

 the ventral pouch are very much enlarged, separated by a narrow network of the ground-color; chin 

 and throat with an irregular patch of olive; streaks across eye very distinct; spots on sides of snout 

 generally brown, the color very different from that of the spots on the body. 



Life colors of a young individual from Apia, dark olive with blue spots; blue stripes on head and 

 a black blue-edged ocellus at base of dorsal; caudal with pale blackish cross-streaks. 



1309. Canthigaster papua (Bleeker). New Guinea; East Indies. 



1310. Canthigaster jactator (Jenkins) . Hawaii; Laysan. 



This species, profusely covered with large pale spots, was found on the reef about Honolulu. The 

 specimens called by Steindachner Tetraodon solandri, from Laysan, seem to be the same. A very near 

 relative is Canthigaster punctatissimus from the Panama region and the Galapagos. 



1311. Canthigaster bitaeniatus (Jenkins). Hawaii. 



f Tetraodon caudofasciatus Giinther, Cat., vin, 304, 1870, no locality with plate. 

 Tetraodon caudofasciatus, Steindachner, Denks. Ak. Wiss. Wien lyOO, 518, Laysan. 

 JEumycteriasbitamiatus Jenkins, Bull. U. S. Fish Comm., xix, 1899 (1901), 400, fig. 12, Honolulu. 



This species is found about Honolulu. In coloration it is almost exactly identical with the com- 

 mon Japanese species, Canthigaster rivulalus Schlegel. In view of the remote habitat, the Hawaiian 

 species may be kept provisionally distinct. 



Apparently the species called Tetraodon caudofasciatus by Steindachner is the same as Canthigaster 

 bitxnialus. The original Tetraodon caudofasciatus of Giinther is from an unknown locality. It may be 

 the same also, as the difference in description is slight. The back is said to be spotted with brown in 

 Cantldgaster caudofasciatus, and the caudal is crossed with dark bands. These traits are not found in 

 Canthigaster biticniatus nor in Canthigaster rivulatus. 



1312. Canthigaster caudofasciatus (Giinther). Laysan (Steindachner, as T. callisternis Ogilby). 



1313. Canthigaster janthinus (Vaillant & Sauvage). Hawaii. 

 Tetraodon janthinus Vaillant & Sauvage, Ann. Mus. 1875, 286, Honolulu. 



This species, an ally of Canthigaster psegma, has not been recognized since it, was originally taken 

 by Ballieu at Honolulu. We should regard janthinus and psegma as identical, were it not that Sauvage 

 describes the lateral spots as large, and the dorsal fin is stated to be black. Only the caudal is black 

 in Canthigaster ]>segma. 



1314. Canthigaster psegma (Jordan & Evermann). Hawaii; Samoa. 



This species has been found about Honolulu and about Samoa. The Samoan examples, four in 

 number, differ a little from the original types, especially in having less clearly defined streaks about 

 the eyes. 



We have two large specimens from Apia. The species is very close to Canthigaster oahuensis as 

 figured by Dr. Jenkins. The markings of the head and fins are almost identical, and the oblong 

 black spots on the sides are the same. But our specimens show no trace whatever of stellate blue 

 spots, and these are very conspicuous in Canthigaster oahuensis. 



Life colors of a specimen from Apia, dark olive with orange-brown shades and faint blue spots; 

 blue and bronze streaks with a few blue specks radiating from eye; cheeks brownish gray with thick- 

 set dark-blue spots above and bronze spots behind them; dorsal and anal pale olive, a black bar across 

 base of each; no black blotch on back; caudal dusky, blackish; pectoral dusky; cheek closely covered 

 with close-set dark spots, which form narrow oblique brown streaks in front; sides of belly with oblong 

 black spots, all smaller than pupil.
