VTP'ER—Trigla lyra. 



28 Pipers were caught, and 25 examined — 6 males and 19 females. In March, 

 4 females were half ripe. In July 1 female was spent. In August, 2 males were nearly 

 ripe, and 3 were ripe, and 1 spent. 14 females were spent. The Piper appears to 

 spawn in the summer, and prohably in fairly deep water, as none were taken in less 

 than 23 fathoms. The eggs are unknown. 



WA.CK'E'R'ELr—Smnber scomber. 



On the 1st April 1 male was half ripe, and 5 were three parts ripe. 9 females 

 were half ripe. All 16 inches in length. On 12th May at Valencia about 50 were 

 examined. All the males were ripe. The females were half and three-quarters ripe 

 mostly, but a few were ripe. At Broadhaven, on 18th June, 17 males at 13 inches 

 were half ripe, three-quarters ripe, and ripe. 15 females of the same size were half 

 and three-quarters ripe, and 1 was ripe, and 1 spent. 4 females, from 9 to 11 inches, 

 appeared to be spent. The pelagic eggs occurred in the tow-nets at the end of April, 

 and the beginning of May, 1891, in the neighbourhood of Boffin Island,^ and off 

 the Skelligs on the 16th, and between Arran and Moher on the 28th May, 1890. 



It appears that successive shoals approach the coast at different points, and spawn 

 in its neighbourhood, the larger fish being the first to arrive. 



SCAD — Caranx trachurus. 



A male and a female were spent on 30th July off the Aran Islands. Day states 

 that spawning takes place in June, July, and August. I examined 2 males and 5 

 females at Penzance on the 16th June. Both males were ripe. Of the females two 

 were half ripe, 2 were three parts ripe, and 1 was nearly ripe. In the last specimen 

 some of the eggs were almost transparent. I concluded that when perfectly ripe they 

 would be pelagic, and similar to that of the mackerel, but smaller.^ 



JOHN TiO-R-Y—Zeusfaher. 



Total number caught, 33. 



Number Examined, 31 — Males 13. Females 18. 

 Number approaching Eipeness, 14 — Males 7. Females 7. 

 Number Eipe 8 — Males 3. Females 5. 

 Number Spent 5 — Males 1. Females 4. 



The remainder of the fish examined were very small and immature. 



' Several thousand mackerel had been taken in a bay on Boffin Island a few days 

 previously, 



2 In the most advanced the diameter was -84 mm., that of the single oil globule 

 •24 to -27 mm.
