of the larva of G. niicrops ; but his drawing of the embryo indicates 

 that the pigmentation of the two forms must be rather similar at 

 the time of hatching. 



Gobius Jeflfreysii. Gilnthcr. 



An old oyster shell, presumably dumped down with other rubbish 

 by a harbour mud-hopper, was dredged on the 3rd July, 1898, about 

 two miles S. by E. of the Plymouth Mewstone in about twenty- 

 three fathoms of water. It was found to be coated on one side by 

 the eggs of a Goby. The shell did not appear to be a recent contribu- 

 tion to the Mewstone ground, while the spawn was in an early stage of 

 development, and may be supposed to have been deposited where 

 found. No Goby was found in the net, but 0. Jeffreysii is commonly 

 taken on the same ground, where it is the only representative of its 

 genus. In shape the ova differ from those attributed to G. pictus, 

 chiefly in that the apex is always rounded and never acuminate. The 

 height varies from -72 to 'TS mm., the greatest breadth from '55 to '58 

 mm. The yolk is practically colourless. We have no observations of 

 more advanced stages.

Gobius scorpioides. Collett. 



According to Smitt (Hist. Scand. Fish., Ed. II., i., p. 260) this Goby 

 has hitherto been known from three specimens, of which two, 28 and 

 37 mm. long, were taken by G. 0. Sars at twenty to sixty fathoms outside 

 Stavanger and Hardanger fjords, while the third, 18'5 mm. long, was 

 found by Winther at six fathoms in the S.W. of the Cattegat. 



We are able to extend the range of the species to the British area, 

 having taken a specimen on the 13th July, 1897, in the mouth of 

 Falmouth Harbour at about eighteen fathoms, N. by W. of Anthony 

 point, in a dredge full of dead shells, etc. It is a female measuring 

 21 mm. in total length. The ovaries are much distended, and contain 

 apparently ripe ova loose in the lumen, with the outer layer of the 

 zona everted. 



The ova are mostly ovul or ovoid in shape, but some show an 

 approach to the shouldered condition common to other small species 

 of the genus. Two measure '52 and '60 mm. in height by -42 and 09 

 mm. in greatest breadth, but these measurements do not allow for the 

 expansion which probably takes place when the spawn is deposited in 

 the ordinary way in sea-water, the specimen having been preserved in 

 weak formol before its viscera were examined. The everted outer layer 

 of the zona is similar to that of other Gobies, except that it shows
