When the preliminary note on these fishes was written in 1904, only one relic of 

 this beautiful Palseoniscid had been found at Gullane, namely, the dentary element of 

 the right ramus of the mandible, showing the characteristic dentition, but subsequently 

 four additional examples were obtained by Mr Macconochie. These are — two examples 

 of the entire fish ; another showing the scales of the anterior part of the body in 

 apposition ; while the fourth is the impression of the two rami of the mandible with the 

 branchiostegal rays. Of the two specimens of the entire fish, one (PL II. fig. 1) is 

 especially interesting as being the smallest example of the species which I have ever 

 seen, its length being a little over 3 inches and its greatest depth slightly over 

 1 inch. The other entire specimen is larger, but somewhat distorted in shape. As 

 regards the one showing the flank scales in apposition, with the operculum and some 

 elements of the shoulder girdle, the scales are remarkably smooth and free from 

 striations, but there can be no doubt as to the correctness of the specific determination.
