I follow Klunzinger in regarding his P. biserialis distinct from 
P. tetricus, Richardson, but consider that it is identical with 
P. bostockii. Waite united the latter with P. tetricus, but they appear 
to differ in the arrangement of the scales on the cheeks and in the 
form of their fins. 
MUCOGOBIUS, gen. nov. 
Body oblong, compressed behind. Head a little compressed, 
scaleless, but with many horizontal and vertical raised mucous 
ridges, which also extend on to the body ; no true barbels. Snout 
rounded, lower jaw the longer ; mouth oblique. Eyes large, close 
together. Opercles unarmed. A band of simple villiform teeth in 
each jaw, the outer ones somewhat enlarged ; vomer and palatines 
toothless. Tongue rounded. Isthmus broad. Scales moderate, 
largest posteriorly, cycloid. Dorsal with six spines and about ten 
rays. Anal similar to the soft dorsal. Ventrals I. 5, united, not 
adnate to the belly. Pectorals pointed, without free silk-like rays. 
Caudal rather lanceolate, produced.

Gobius mucosus, (Gunther), Waite — Rec. Austr. Mus., VI., 1906, p. 200. 
The collection includes three from Fremantle, while another 
was collected by Mr. Abjornssen near Albany. 
I am unable to associate this species with any genus known to 
me, and therefore propose Mucogobius for it as above.

The genus Sebastapistcs, is apparently distinguished from 
Scorpaena only by the armature of the preorbital and its smaller size. 
Some large Australian species have strong recurved spines on the
