•039 to -0435 in., as before. Eggs of ling. Eggs of dab, some of '033 in. 
with botryoidal blastoderm (pleuronectid 1). 
Station IX. — Bottom. Motella-\\ke post- larval form, 4 to 5 mm. 
Cottiis-\\\iQ with black pigment on head and tail. 
Larval form with four large oil-globules, which, however, may have been 
caused by rupture of single globule (? pleuronectid with single oil-globule). 
No locality, no date. Eggs of dragonet, rockling, dab-like, though 
smaller, "027 in., and another, -0255 in. 
Eggs of dragonet, little sole C^), "024 in., rockling, witch, '0285 in., 
with accompanying larva ; young dragonets. 
No date no locality. Young gobies about 5 '5 mm. ; young rockling, 
5*8 mm., with long ventrals. 
27 fathoms. Larvse of bimaculated sucker, with oil-globules in yolk, 
and a considerable amount of black pigment in the skin. 
Jura West. — 26th June 1890. Trawl at 20 fathoms. Young lump- 
suckers, 10 to 20 mm. ; green cod, 42 mm. ; young gunnels, 28 to 31 
mm. ; and bimaculated suckers, 21 mm. 
Loch Scridain. — June 1890. Bimaculated sucker. 46 mm. 
Loch Scridain. — June 1 890. Young conger (' Leptocephalus '), 80 mm. 
In this the lateral line has a row of black chromatophores of the ordinary 
structure from behind the pectorals to the tail, ventrally a double row 
(somewhat widely separated) of black chromatophores to the commence- 
ment of the anal fin, where the rows approach each other, and have 
between them a median row at the base of the fin. The dorsal comes 
far forward, reaching within | in. of the tip of the snout, but still far 
behind the tip of the pectorals. No black pigment-specks occur at the 
base of this tin. Both anal and dorsal fins have permanent rays. The 
tail resembles that of the adult. The gill-slits are almost ventral. The 
eye is larger than in the common eel of the same size, and the shape of 
the body different. 
11. Frith of Forth and East of May Island. 
Station VII. — Bottom, 15th April 1890. Larval cod and pleuro- 
nectids. Herring, 14 mm.; pleuronectids, 8 '2 mm., left eye advanced and 
appearing on ridge. Montagu's sucker, 10*5 mm. 
Cross-Section I. — 14 fathoms, 18th April 1890. Young cod, 5 mm. ; 
young sand-eels, 14 to 16 mm. ; post-larval flounders, 7 to 8*5 mm. ; post- 
larval Montagu's sucker, 4*5 mm. 
Station I. — Bottom, 18th April 1890. Larval cod, 4 mm. ; young 
sand-eel, 8*5 mm. ; Montagu's sucker, 4 mm. ; post-larval Cotius, 6 mm. 
Attached to a fold of the intestine of a ripe female gurnard at this 
Station, on the 15th April 1891, were a number of baccate structures 
about the size of " six " or " seven " shot. These were formed of layer upon 
layer of glistening membranous tissue, surrounding minute parasitic ova. 
In one of the larger masses a minute Ascaris was present, so that in all 
probability the ova are connected with this form. 
Station IX. — Surface, 24th April 1890. Ova of cod and haddock in 
considerable numbers ; many eggs of long rongh dab, with embryo well 
developed ; eggs of bib, plaice, whiting, sprat, dab, and others. 
Station V. — Surface, 25th April 1890. Eggs of rockling — two sizes 
as before ; egg of gurnard ; eggs of sprat. 
Station Vllf.— Bottom-net, 26th April 1890. Pleuronectid, 11 mm. 
(probably plaice), with eye on ridge. 
West of the Island of May. — Surface, 29th April 1890. Young 
Cotti, 7 to 9*5 mm.
