[65] REVIEW OF THE LABROID FISHES. 663 



ranged in three or four rows on the upper margin, large and in a single row below ; 

 center of theopercle naked; lateral line nearly parallel w ith base of dorsal for a dis- 

 tance of 30 scales, where it drops sharply, the last 10 scales being in a horizontal 

 line ; last scale of the lateral line much lengthened; scales of nape and throat 

 small. Color reddish brown ; a small, diffuse, dark blotch upon the first three 

 dorsal rays; a second larger one, dark blue in color, generally present between 

 the 19th and 22d soft rays of dorsal ; a small, indigo-blue cross streak at base of 

 pectoral; sides of body reticulated with dark brown lines, their junctures form- 

 ing a little spot at base of each scale. Head 3f in length ; depth 4f . D., Ill, 29 ; 

 A., 11,19; scales 4-40-10.] (Steindachner.) Reticulatus, 75. 



75. MALAPTERUS RETICULATUS. 



Malapterus reticulatus Cuv. & Val., xiii,355,pl. 383, 1889 (Juan Fernandez); Gay, 

 Hist. Chili, Zool., ii,301 ; Steindachner, Ichth. Beitr. iv, 62 (Juan Fernandez). 



Malacopterus reticulatus Giinther iv, 88 (copied). 



Neolabrus fenestratus Steindachner, Ichth. Beitr., ii, 19, 1875, with plate (Juan Fer- 

 nandez). 



Habitat.— Coast of Chili. 



Etymology: Reticulatus, reticulated. 



This singular species seems to be rather rare on the cost of Chili. As 

 Steindachner states that there are constantly but three simple, flexible 

 spines in the dorsal fin, we find it necessary to remove the genus from 

 the Labrinw, where Giinther has placed it, and from the Julidinw, where 

 Steindachner has left it, and to makeof it a separate group or subfamily.* 

 If, as seems probable, the number of vertebra) is more than 30, the 

 nearest allies of the Malapterinw would be the Labrincc. We know this 

 species from descriptions only. 



Genus XXV.— CKYPTOTOMUS. 



Calliodon Cuvier, Regne Animal, 1829, Ed. ii. (spinidens) (not of Gronow, nor of Bloch 

 & Schneider). 



Callyodon Cuvier & Valenciennes, xiv, 285, 1830 {spinidens, ustus, etc.). 



Cryptotomus Cope, Trans. Am. Phil. Soc, 1871, 462 (roseus). 



Type: Cryptotomus roseus Cove. 



Etymology: KpuizToq, hidden; ro^oc, cutting (teeth). 



This genus is closely related to Sparisoma, differing from it in having 

 the anterior teeth nearly separate at all ages and in having the dorsal 

 spines flexible, as in Scarus. The dentition approaches that of a very 

 young Sparisoma. 



The genus Calliodon of Gronow and of Bloch & Schneider was based 

 on a species which apparently belongs to the genus Scarus. The name 

 was transferred by Cuvier from the type of S. croicensis to the present 

 group. This transfer is inadmissible in our view, and the name Callio- 

 don should not be used for the genus. Callyodon, a variant spelling of 

 the same word, is apparently also inadmissible. 



The name Cryptotomus was proposed by Cope for a fish having the 

 " dentition of Callyodon, but with the numerous dorsal and anal spines 

 of the group of Harpe." The fin rays are given D., XT, 8 ; A., Ill, 8. The 

 numbers in all known species of Scarince are D., IX, 10; A., Ill, 9 (8).
