Callionymus lyra L. 



Heiford recorded the eggs of the dragonet from 11th February to 

 30th August, but they have been observed this year in January. There 

 is thus an indefinitely prolonged spawning period in the Plymouth 

 district. This is borne out by the post-larval records, which extend from 

 March to September, with a maximum for the middle months of the 

 year — May, June, and July. The distribution of the post-larvse is 

 general, but there is a distinct concentration in numbers between the 

 twenty and thirty fathom lines, where the adults are also very numerous. 

 The frequency is low inshore within the twenty-fathom line. Between 

 the ten and twenty fathom lines, and also between the thirty and forty, 

 the percentage is fairly high, and shows only a slight decrease from the 

 numbers in the area included between these two regions.

Lepadogaster himaculatus Donov. L. gouani Lacep. L. candollei Eisso. 



The distribution of these three species is well marked by the records 

 in Table 24. There are two types represented — the littoral type in 

 L. gouani and L. candollei, and the deeper water type in L. himaculatus. 

 The frequency of L. himaculatus is high beyond the twenty-fathom line 

 and low in depths less than twenty fathoms. Post-larval L. himaculatus 

 occurred from June to September with a maximum in July. Spawning 

 thus begins in May and extends to August. Ova were frequently found 

 in June and July attached to the inside of empty pecten shells taken in 

 the otter trawl on the Eddystone Grounds. Adult males were generally 

 in attendance.
