the ship at Colombo, and remained in her till the 4th May, 

 when she went into dock at Bombay. Altogether there were 

 twelve trawls made in over 100 fathoms, yielding a fair 

 number of Crustacea, Fishes, Mollusca, &c. Of these the 

 Fishes and Crustacea have been identified, while the Worms 

 and Mollusks remain still to be described by the specialists to 

 whose hands they have been entrusted. 



Of the most interesting finds made during the year may be 

 mentioned : — 



1. A very large specimen (an adult male), 12 inches long, 

 of Bathynomus giganteus, A. M.-Edw., dredged off the north- 

 west of Ceylon in 594 fathoms. 



2. A specimen of that strange crab Trichopeltarium ovale, 

 from a depth of 445 fathoms. 



3. Five specimens of the Atlantic fish Hophstethus atlan- 

 ticum. 



4. A trawl of twenty-eight specimens of Glyphocrangon 

 investigatoris. 



5. Two fine specimens of Pennatula from 487 fathoms, in 

 the branches of each of which was found a small polychaite 

 worm of one and the same species. 



6. Two specimens of Pleurotoma sgmbiotes, from 771 and 

 464 fathoms. As on the two previous occasions on which 

 this interesting mollusk was dredged, the same species of 

 Epizoanthus was found encrusted on the living shell. 



7. A large collection (forty-five specimens) of Turbo I'ndicus, 

 from 595 fathoms. The living shells were generally covered 

 on the spire by Scalpjellum and sponges. 



8. Two fine specimens of a species of Conus were found at 

 the very unusual depth of 487 fathoms. 



Most of the Crustacea obtained had been previously known, 

 but the following three species are new : —
