1903.] NATURAL SCIEXCES OF PHILADELPHIA. 333 



A pale purplish streak below the base of the pectoral. A purpUsh 

 Y-shaped bar on the opercle, with narrow pale blue margin, and with 

 a deep violet-blue spot above. Upper Up oUve-green. Cheek pale. 

 Mandible with two brownish-purple cross-bars narrowly bordered with 

 pale bluish. Dorsal fins dilute orange, basally dusky, with greenish 

 spots narrowly margined with pale bluish. Anal similar, grapsh, 

 and with dull rosy tints. Caudal deep orange-red, marginal portion 

 of the fin blackish, and with pale oblique bluish stripes. Axil of 

 pectoral pale green. Iris bright orange edged with green. 



One example 8f inches long, from lower Biscayne Bay. I am not 

 certain that my fish is identical with Bloch's account, as it also does not 

 agree with his figure. Lacepede's account is less satisfactory.

13. Cheilichthys testudineus (Linnseus).* 



1758. [Tetraodon] testudineus Linnaeus, Sj'st. Nat., Ed. X, p. 332; in India.^ 

 Color in alcohol dark slaty-brown, the sides gradually becoming 

 whitish below with a dull ochraceous tinge, especially along the lower 

 side of the head. Large deep blotches of blackish-brown on the back, 

 made up of clusters of crowded spots which leave winding paler lines 

 between. On the sides these spots become separated and are very 

 distinct against the paler background. Axil of the pectoral brown. 

 Fins dull dusky with an indistinct tinge of dilute olivaceous, except 

 the anal which is white. Lower surface of the body chalky-white. 

 Iris yellowish-gray. 



One example 8f inches in length, lower Biscayne Bay.

* Cheilichthys is given generic rank for those American forms with a broad, 

 flattened, or "only slightly concave interorbital space. Type Tetraodon testu- 

 dineus Linnseus. 



^ The type of the species probably came from tropical America. The rude 

 accounts of Clusius and Willughby throw little light on the subject. I have been 

 unable to consult Dr. Gunther's reference, " Tetrodon testudineus, L. Amoen. 

 Acad., i, p. 309, tab. 14, fig. 3." The edition of Amoenitates Academicse, etc., 

 in the Academv's librarv, has an account of Ostracion oblongus glaber, etc., by Balk 

 (1749, p. 591).' It is based on Artedi, Willughby, Clusius, Ray and Sloan, and no 

 locality is given. If, however, Linnaeus sliould be found untenable, Tetrodon 

 geometricus Schneider is the next name available with certainty. 



^ This name is transposed from the original.
