but this is reduced to an average of 25 9r in trans- 

 forming specimens and to 22% in a newly trans- 

 formed juvenile. The eyes are round or nearly 

 so in Scopelopsis; eye width, measured hori- 

 zontally, averages 92% of eye length for the 

 larval series. In the 17.4-mm juvenile, the hor- 

 izontal measurement is slightly greater than the 



vertical. Choroid tissue is absent from the vent- 

 ral surface of the eye. The initial lateral teeth 

 of the lower jaw are characteristically curved an- 

 teriad. Later, the more typical dentary teeth 

 form anterior to the curved teeth; the latter oc- 

 cupy the posterior half of each dentary in larger 

 larvae.
