This fine and well-marked species was observed in 86 tow-nettings, 32 of which 

 were surface and 51 under-surface collections. The depth of the under-surface 

 tow-nettings ranged from 2 to 460 fathoms. 17 of the surface and 39 of the imder- 

 surface tow-nettings were day collections, while 15 surface and 15 under-surface were 

 night collections, as shown in the annexed formula : —

Corycceus speciosus was one of the more common species of the Gorycceidce observed 

 in the collection, but it was not obtained in any gathering from localities where the 

 water was of a decidedly brackish character, as at Bananah Creek. The remarkably 

 divergent caudal stylets made this an easily recognized species ; several specimens were 

 obtained with ovisacs.
