THE FISHES. 



195 



111 the Irish collections this tish is common in nets lowered to considerable depths. 

 We know of no record which jjroves its occurrence, in Atlantic or Pacific, at much less 

 than 265 fathoms. 



Fish-remains from the following- hauls, 32<7, 32 o, 34/, 35 c, may possibly be referable 

 to this species. If, in fact, so referable they considerably extend its proved upward 

 vertical ranae. 



The following larva appears to us to be clearly referable to Boulenger's subfamily 

 GonosiomatiniB. 



" Pb-escope " Larva. (Figs. 2 & 3.) 



Yis. 2. 



" ProEseope " larva 1.5 mm. long, x 10 ca. 

 Ks. 3. 



" Preescope " larva 9 mm. long, x 17'5 ca. 



Specimens of this form occurred in the following hauls : — - 



24 6. One of 1.3 mm. 35 d. One of 9 mm. 



"Me. Two of 15 mm. 



Small elongate larv;e, of which some may probably be identified with this form, occurred 

 in one of the above hauls and five others, all fished from between 100 or 50 lathoms and 

 the surface at various hours of the day and night. None of these latter larvae, however, 

 liave any characters of a nature sufficiently definite to permit of their reasonably certain 

 association with this form. 



The evidence of vertictil range is too slight to permit of any conclusions being dra^ii, 

 but it is worth noting that the " Pricscope " larva has not been found in any haul 

 commencing nearer the surface than 50 fathoms and only certainly identified in liauls 

 commencing at 100 fathoms. This form has not been recognized by us in any of the large 

 collections made by the ' Helga ' in deep water off the west and south-west coasts of 

 Ireland, and we accordingly append a somewhat fuller description than in the cast; of 

 larvae of which we may reasonably anticipate a fuller material in the near future.
