Figure 10. — Distribution of larvae of the myctophid Hygophum proximum (Becker) and of the bothid flatfish 

 Bothus leopardinus (Giinther) on EASTROPAC I. Records of occurrence of larvae of H. proximum are 

 shown as open circles with dot in center for hauls containing 1 to 25 larvae, and as large solid circles for hauls 

 containing 26 or more larvae; records of occurrence of larvae of B. leopardinus are shown as squares; neg- 

 ative hauls are shown as small solid circles. 



pyrsobolus (Alcock) complex. Larvae of Lepi- 

 dophanes are almost unpigmented, big eyed, and 

 moderately deep bodied. They have few dis- 

 tinctive characters and can be confused with 

 larvae of Diaphus and Ceratoscopelus. The ma- 

 jority of the records for Lepidophayies were of 

 large larvae. 



Lobianchia sp. (16 occurrences, 39 larvae) 



Larvae of Lobianchia were not recognized 

 until the identification of EASTROPAC larvae 



was well underway, hence our records of occur- 

 rences may be incomplete (some but not all 

 samples were rechecked subsequently). The 

 head of Lobianchia larvae is more massive than 

 in most myctophid larvae. The most diagnostic 

 feature, however, is the unusual manner in 

 which the pectoral fins develop: the upper fin 

 rays in each iiectoral develop sooner than the 

 remainder of the fin rays and become conspic- 

 uously elongated (Taning, 1918). Twelve of 

 the 16 occurrences were in the pattern worked 

 by Alami^ios and half of these were at adjacent
