 Straaleantallet varierede saaledes hos de 8 Individer 



i Iste Dorsal mellem 10 og 11. i 2den Dorsal mellem 15 

 og 17. i Analen mellem 16 og 18. De 2 Dorsaler vare 

 bos enkelte fuldstændigt sammenstødende. medens de hos 

 de fleste vare fjernede fra hinanden ved et kort. men tyde-

Blot 2 af de erholdte Individer vare Hanner, og 

 havde en forholdsvis lang Analpapille. 



Hos de 2 mindste var Hovedet endnu glat. men hos

 The number of fin-rays in the 8 examples varied 



accordingly: — 1st dorsal, between 10 and 11; 2nd dorsal, 

 between 15 and 17; anal, between 16 and 18. In one 

 or two of the specimens the dorsals were contiguous, in 

 mOst however separated, the space between, though short, 

 being distinctly obvious. 



Two only of the specimens obtained were males, and 

 had a rather long anal papilla. 



In the two smallest individuals the head was as yet 

 perfectly smooth; but the frontal region and the preoper- 

 culum of the largest were furnished with a cluster of depressed
