either. The cæca situated where the duodenum usually occurs were 
plainer, but not so decided in character as to be unmistakable. The 
ovaries however were present and very full of nearly ripe ova, very 
red and about the size of sago piles. The roes measured in inches 
2-5 x 1:0 x 0-8, the cross section being in shape a sector of a circle 
of which radius and arc in size are represented by 1:0 and 0:8 in dimensions 
just given. A distinct strong ovary duct connected the ova sacs with the 
vent, the external end forming that opening. The abdominal cavity was 
full of excreta, similar in its dark colour and offensive odour to that found 
in mouth of the first specimen I have described. The stomach, exactly 
similar in form to that above-mentioned, contained fourteen egg-like or larval 
bodies, almond shaped, white, and with hard cores a quarter to half inch 
each in length enclosed in a stringy spiny mass, with a few remains of 
shrimps. No air-bladder present. Liver large and heart lay right under- 
neath the lower pharyngeals. 
This species is rather loathsome-looking and has not the appearance 
of a good edible fish.

This specimen of a blenny was caught off Otago Heads, May 6th, 1884, 
and I have made a life-size drawing of it for comparison, by which it may 
be seen to differ in greater robustness from any I can find figured in the 
Transactions of the Institute. In form the head is contained a little more 
than four and a half times in the total length ; trunk compressed slightly 
and deep, greatest depth goes three-and-a-half times in total length, 
and is in vertical from third spine of second dorsal fin. The sub- 
opercle is prolonged into a sharp spine at posterior margin, which lies 
exactly on origin of lateral line. Mouth protractile, jaws equal and 
cleft very oblique. Intermaxillary in front of and not articulated 
with maxillary; maxillary with triangular or club-shaped free end. 
Teeth villiform and fine, present on maxillary, mandible, palatines, 
and head of vomer. Eye large, lateral and close to interorbital space, 
pupil and iris dark red with a small bright silvery spot on inferior margin of 
iris. Membrane of branchiostegous rays confluent with opercles. First 
dorsal fin detached and erect like a crest above the head, second and third 
continuous ; spines mostly soft, but not branched in dorsal pectoral and 
anal fins ; ventrals jugular, ete., consisting only of two bare rays. Caudal
