GENUS ENTOMACRODUS — SPRINGER 



115 



pores terminating on side in area below and between dorsal fin spine 

 11 and ray 3 (usually between spine 12 and ray 1); ventral margin of 

 upper lip crenulate on lateral thirds, entire on middle third; lip crenulae 

 numbering 6-13 on each side (usually 7-10). 



Proportional measurements: See tables 3, 4, and 53. 



Only two males, 72.7 and 85.3 mm SL, were seen with fleshy rugose 

 modifications of the skin of the anal spines and rays (first four rays). 

 If one considers males with these modifications mature, then mature 

 males occurred in the same collection with immature males as large as 

 100.5 mm SL. 



Below 85 mm SL, males and females occur in collections with rela- 

 tively equal frequency at various sizes; however, the largest female 

 examined, 83.7 mm, was somewhat smaller than the largest male,. 

 100.5 mm. Males larger than 84 mm are relatively common, indi- 

 cating that males generally attain a larger size than females. 



Color pattern of preserved material. — -None of the material 

 available to me was less than 50 years old and much of the color pattern 

 in this material has been lost. The specimen illustrated in plate 21 

 shows a color pattern more clearly than any of the other available 

 specimens but seems to be somewhat atypical in the evenness of shade 

 of the body bands. In other specimens with preserved patterns, there 

 appear to be indications of 6} 2 to 7 pairs of bands on the body. There 

 are no indications of fusions between the mid portions of the members 

 of a pair, except possibly the anteriormost, shortest pair in the region 

 above the pectoral axil. In many specimens the bands appear to have
