at >3,6 mm between 9 and 11 DAH. The second spine of the 

 dorsal fin was first to develop followed by the third, then 

 the first and fourth spines. Development of the remaining 

 dorsal-fin elements proceeded posteriorly; the tenth dorsal 

 spine initially formed as a raylike element. Fine serrations 

 were present on the leading edge of the pelvic spine at 3,8 

 mm ( 12 DAH ). Anal-fin development began by 3.6 mm ( 11 

 DAH ) and by 3.8 mm ( 12 DAH I the first anal spine began 

 to form. Development of the remaining anal-fin elements 

 proceeded posteriorly; the third anal spine initially form- 

 ing as a raylike element. All fin spines were V-shaped in 

 cross section. Caudal rays were first noticeable at 4.4 mm 

 (13 DAH) and pectoral-fin rays began forming at 5.5 mm 

 ( 15 DAH). By 9.6 mm ( 17 DAH), all elements in the dorsal. 



pelvic, and anal fins were formed. Formation of pectoral 

 rays and both principal and procurrent rays of the caudal 

 fin was completed by 12.2 mm. 



Pigmentation (Figs. 1-5) Head Small melanophores 

 were scattered over the head of day-old yolksac larvae at 

 2.5 mm. These melanophores were not present in 3 DAH 

 larvae but small melanophores were present in the otic 

 capsule of 2.6- and 2.8-mm larvae (3 and 5 DAH). A mela- 

 nophore appeared over the midbrain at 3.6 mm and with 

 development, both internal and external head pigment 

 increased until at 9.6 mm, most of the surface of the head 

 above the midbrain was covered with small melanophores. 

 Pigment on the surface of the head over the forebrain was
