86. Haliclioeres dimidiatus (Agassiz). {JuHs internasalis Foey.) 



These specimens agree well with those from Cuba described in Proc. 

 U. S. IN'at. Mus., ISSG, 62. The blue band from eye to nape is broader 

 behind and it is edged everywhere by deeper bine. This species is 

 probably the Labrus cyanocephaJns of Bloch, as (yastelnau has suggested, 

 but the figure is too poor to permit identification. 



All the American species of HaUchoeres agree in having the anterior 

 canines f. Most of the E ist I'ldian species of this group have the 

 canines | and none of them f . This character might be taken to define 

 a subgenus or genus containing all the American species, hitherto 

 referred to, Plati/glossus^ Chwrojulis or Haliehoeres. The name Ichtliy- 

 callus was applied by Swainson to a number of species of J'?th"<:?inrt\ dis- 

 tinguished from the others by fallacious or imaginary characters. As, 

 however, B. dimidiatus is the species first named by Swainson, it may 

 be taken as the type of Ichthycallus, and the name may be used to 

 designate these HalichwreH with the teeth |. These are radiatns, 

 nichoisi, seUi/er, dimidiatus, garnoti, maculipinna, bivittatus, dispilus, 

 poejii, and caudal is. 



87. Haliehoeres poeyi (Steiiulacbner). (Jtdis crolaphua C. & V., not of Cuvier.) 



Three specimens. This species is probably distinct from the one 

 which I have heretofore called Haliehoeres or Platyglossus caudalis. The 

 form of the caudal fin is the same and both have the black si)ot behind 

 the eye. H. yoeyi is, however, deeper in body, and the snout is decid- 

 edly less acute. Depth, 4 in length ; snout, 2f in depth of body. 



In spirits, if. j:>oej/t is pale, with traces of three dark cross-shndes 

 with paler interspaces; some traces of blue spots on scales; a blue 

 streak forward from eye ; a dark blue spot behind eye; above this a 

 golden spor, very distinct in two specimens but obsolete in the larger 

 one. Base of pectoral, bluish ; an ink-like spot at base of last dorsal 

 ray. No marks evident on the fins. 



These specimens agree fairly with Steindachner's account of Platy- 

 glossus poeyi (Ichth. Notiz, vi, 49, 1867), except that the eye is larger. 

 Steindachner says, "Das Auge ist klein, C.J mal in der Kopflaiige, mit 

 Einschluss des hiiutigen Lappens * * * ^jie Schnauzenliinge bis 

 zum Oberlippeuraud fast drei Augenlangen." In our examples the 

 snout is barely twice as long as the eye. 



88. Xyrichthys splendens Castehiaii. (Xijrichlhy.s arfjoitimaciilaltis Steindachner.) 



Two adult, one young example, one of the adults being from near 

 Cape San Roqne (station 2759, 7° S., 34° 47' W.). The figure given by 

 Castelnau is fairly correct, especially as regards form of the body. This 

 is a dee]), compressed species, with a bluntish, evenly rounded profile, 

 which is scarcely trenchant, the species being therefore intermediate 

 between the typical Xyrichthys and Novaculichthys. Eye, If in width of
