136 NOTES OxV THE REPRODUCTION OF TELKOSTEAN FIStlES 



with the northern form. Both British and Mediterranean examples are 

 ilhistrated in my paper in the Annalcs. So far as I know, large 

 difl'ercntiated Scaldfish have never been observed at Marseilles, though 

 they are known from other parts of the Mediterranean. 



Arnoglossus Grohmanni. Bo7iap. 



Raffaele, F., Mitthcil. Zool. Stat. Neap., viii., 1888, p. 49, Tav. iv. Larva hntchcd 

 from tow-net eggs resembling those of various species of Arnoglossns, Rhoin- 

 loiclicMhys, and Citharus. 



Holt, E. W. L., Annales Mus. Mars., v., 1897, Fasc. I., Note 4., p. 33. Pre- 

 liminary notice of egg and larva provisionally referred to A. Grohmanni. 



Holt, E. W. L., ibid., v., 1898, Fasc. II. Ova and larvce, Mediterranean and 

 British, referred to A. Grohmanni ; ivith figures. 



In all, eight specimens of A. Grohmanni were trawled by the Busy 

 Bee in 1897 and in January, 1898, viz., six at Plymouth and two in 

 Falmouth Bay. The latter, taken on the 8th July, were females, very 

 nearly ready to spawn. The species can no longer be regarded as 

 extremely rare on our south-western coast. I have never noticed it 

 among the large numbers of large A. latcrna which have been brought to 

 me from the off-shore trawling grounds ; it seems rather to prefer the 

 neighbourhood of rocks or rough ground nearer the shore, and may 

 perhaps be common in actually rocky places inaccessible to trawling. 



I associate with this species ova measuring '67 to "68 mm., oil-globule 

 •12 to "13 mm., at Marseilles, and "72 and '74 mm., oil-globule "12 mm., 

 at Plymouth. The Plymouth specimens, with another not measured, 

 occurred in July. 



The larva, which is certainly that figured by Raffaele {loc. cit.), is 

 readily distinguished from A. latcrna by the presence of two post-anal 

 pigment bars or patches, of which the last is near the caudal extremity. 

 A. laterna, apart from some pigment sometimes present about the origin 

 of the tail, has only one, approximately median, post-anal band or patch 

 of pigment. 



The pigment is perhaps more vividly red or orange in A. Grohmanni. 

 In creneral conformation, in the unicolumnar character of the notochord, 

 in the presence of digitiform cells along the edge of the marginal fin, 

 and in the frequently reticulo-papillate condition of the skin, the two 

 larvfc are identical. A newly-hatched larva of A. Grohmanni (Ply- 

 mouth) measures 2-32 mm. Allowing for individual variation in the 

 decree of development at v/hich hatching takes place, Mediterranean 

 examples appear to be of about the same size, or a little smaller. 



By those who may still regard A. laterna and A. lophotes (the large 

 form with elongated dorsal rays) as distinct species, it may be suggested 

 that the larva which I refer to A. Grohmanni may be really that of
