third spine 1% to iVe, fourth ray 1)4 to 134; least depth of caudal 

 peduncle 2% to 3; caudal truncate to slightly emarginate, slightly 

 convex as expanded, l^ to 1%; pectoral 1 to li^; ventral 1 to l^- 

 Very pale brownish generally. Broad brown band includes predor- 

 sal, eyes, muzzle and chin; broken with pale loop up from nostrils to 

 middle of interorbital and down on other side; pale transverse band 

 across occiput below supraocular tubercle to upper eye edge. Second 

 broad blackish-brown band from middle of spinous dorsal down to 

 include pectoral base and most of post ventral space. Third trans- 

 verse band obliquely from hind part of soft dorsal obliquely across 

 tail to posterior half of anal. Anal narrowly bordered blackish. 

 Pectoral pale or whitish. Ventral black. 



Mauritius, East Indies, Riu Kiu, Polynesia. An examination of 

 the type of Loa excelsa and a comparison with the figures published 

 and purporting to represent it are worthy of some comment. Appar- 

 ently Heniochus macrolepidotus (not Linnaeus) Brevoort,^ represents 

 an example 44 mm. long. In a general way it differs in that its 

 depth is shown as 2 {Loa excelsa with Ij^), fourth dorsal spine long- 

 est (Loa excelsa with third longest), dark ocular band extends along 

 hind eye edge to cheek (crosses eye medially in Loa excelsa) , only 

 one transverse black band in the body though begins at longest 

 dorsal spine and reaches breast before ventral origin. We feel con- 

 vinced, however, that Brevoort's figure represents inaccurately his 

 specimen. The absence of the dorsal ocellus and the broad dark 

 vertical band across the tail from the last dorsal spines and soft 

 dorsal to the hind part of the anal, may well have faded from his 

 specimen. Brevoort is careful to state that "the second black band 

 does not touch the opercle and the third unites with the second 

 under the spinous dorsal," the latter statement evidently an error? 

 Brevoort gives the dorsal as X, 24. 



Bleeker's figure is from an example 90 mm. long from Java, but it 

 is given with D. XII, 28; A. Ill, 19. It is shown without the dark 

 transverse bands, but his description of them agrees with Loa excelsa. 

 As the ocellus is not mentioned it had probably disappeared. The 

 figures by Cuvier and Gunther show the adult, in which the fourth 

 dorsal spine is greatly lengthened.
