GENUS ENTOMACRODUS — SPRINGER 



87 



Color pattern of iiolotype. — Male. The sides of the body 

 are delicately marked with scattered melanophores. There are a 

 few loose concentrations of melanophores on the sides which give 

 the appearance of spots. The head is more or less uniformly covered 

 with scattered melanophores. The upper lip has indications of 

 five dark stripes separated by dusky interspaces. The spinous 

 dorsal fin is irregularly dusky. The soft dorsal fin bears about three 

 dusky spots are over each ray arranged in diagonal series from ray 

 to ray. The anal fin is irregularly dusky distally, unmarked basally, 

 on its anterior half, and completely unmarked on its posterior half. 

 The caudal fin bears four or five rows of irregularly vertically ar- 

 ranged spots concentrated at the rays. The pectoral fin, its fleshy 

 base and the pelvic fin are lightly covered with scattered melanophores. 



The paratypic males are similarly marked to the holotype. The 

 females are also similar but the dorsal fin bears fewer marks, the anal 

 fin is immaculate, and the lateral stripe on either side of the upper 

 lip is broader and more bandlike than the stripes in the same position 

 on the lips of the males. 



All in all, this is an inconspicuously marked species. 



Relationships. — In spite of the fact that it shares certain characters 

 with various other species of Entomacrodus , I find it difficult to relate 

 E. rqfeni closely to any of the other species. Its rather high vertebral 

 number (35) is found commonly only in: E. vomerinus, E. stellifer 

 (from both of which it obviously differs in disposition of dorsal lip 

 crenulae and nature of supraorbital cirri), E. marmoratus (from which
