NOTES AND MEMORANDA. 285 



trawled off Stoke Point in about 25 fathoms, which corresponds to 

 the description given by Hubrecht* of Garinella polymorpha. 



Hubrecht's description is as follows : — " Differing from the fore- 

 going species (C. annulata) by the form of the head, which is still 

 wider and more hammer-shaped, as well as by colour, which is always 

 a uniform reddish or orange-brown/' 



This species is synonymous with Valencinia splendida of 

 de Quatrefages, and Tubiilanus polymorpha of Renier. It has never, 

 I believe, been found before on the British coasts. Its geographical 

 extension, as given by Joubin,t is Banyuls, Roscoff, Brehat 

 (de Quatrefages), Naples (Hubrecht), Adriatic (Dewoletzky), ocean 

 and Mediterranean (Vaillant). Mcintosh, in his monograph, 

 describes a worm from the island of Herm, which is perhaps identical 

 with this species, but which he regards as a variety of Oarinella 

 annulata. 



Neither Hubrecht nor Joubin mentions the existence of extremely 

 faint lines, which are quite similar in position to those of C. anriulata, 

 except that the median ventral line seems absent. They are so 

 faint that it is with great difficulty that they can be seen at all, 

 and they in no wise interfere with the uniformity of the orange-brown 

 colour, which seems, except on very minute inspection, to be un- 

 interrupted. In the Garinella from the island of Herm, Mcintosh 

 mentions the existence of a pale lateral line on each side, and faint 

 traces of transverse bars on the dorsum. — T. H. R. 



Cultureof Sea Fish.— From the Annual Report of the Newfound- 

 land Fisheries Commission for the year 1891, presented to the 

 Legislature March, 1892, the following interesting extracts are 

 taken. Speaking of the Dildo hatchery, the Report says : — " Bv 

 July 25th there were 616 codfish in the wells. The total number 

 of ova stripped from these fi.sh was 78,950,000. Of these, 

 39,650,000 were rejected, and -39,650,000 were hatched and planted 

 in a healthy condition. This gave the satisfactory yield of 502 per 

 cent. During the month of December an important improvement, 

 which had been in contemplation from the first, was carried out at 

 Dildo — namely, the construction of a salt-water pond, in which the 

 codfish will be placed to spawn in the natural way, instead of under- 

 going the process of stripping. This pond is 47 feet in length and 

 23 in breadth, and is most substantially built of stone and Portland 

 cement. There is a specially constructed collector and otherapparatus 

 to gather up the ova as they are extruded from the fish, and fertilized ;
