shaped, and one wliose base occupies the whole anterior end of tlie 

 infraorbitar on each side, projects boldly lieyond the snout, and gives 

 the fish a very different aspect from any other known gurnard. 

 The other may be thus characterized ; —

Trigla Vanessa has a spinous infraorbitar tooth, larger than usual 

 in gurnards, though not so remarkable as in the preceding species, 

 and not occupying the whole end of the bone, there being a smaller 

 tcoth and some granulations beneath it. The arming of the dorsal 

 furrow extends to both fins, and is formed by saddle-shaped dilata- 

 tions of the interspinous bones, with a triangular spinous tooth on 

 each side of each plate directed backwards. I'he scales of the body 

 are rather large, and are studded on their uncovered portions with 

 minute spiny points ; those forming the lateral line are tubular both 

 transversely and longitudinally, and are armed with several strong 

 spines also tubular. There is a black mark on the anterior dorsal. 

 The sides of the head are finely granulated without radiations, and 

 there are no denticulations on the edge of the orbit either in this or 

 the preceding species. 



6. Apistes marmoratus (Cuv. et Val. 4, p. 416). The specimens 

 correspond exactly with the description given in the work referred 

 to, except that the first suborbitar has only one tooth anteriorly. 

 The spine of that bone reaches in one specimen to the preoper- 

 culum, but in another it is one third shorter, being In the latter case 

 only just equal to the preopercular spine in length. 



7. Sebastes maculatus (Cuv. et Val.). Two specimens in good 

 order, when examined in reference to the account of the species in 

 the work referred to, offer no discrepancy, except that the postor- 

 bitar spines are somewhat different from those of imperialis, which 

 macidatus is said closely to resemble. S. maculatus is an inhabitant 

 of the seas of the Cape of Good Hope, and although a range from 

 thence to Van Diemen's Land may appear very great, it is not more 

 extensive than that of the northern sebastes which has been taken 

 on the coasts of Greenland, in the gulf of St. Lawrence, on the 

 coast of Norway, and in the British Channel. 



8. Ckeilodnctylus carponemus (Cuv. et Val.), known locally as the 

 Perch, and described as having, when fresh, a bright silvery hue 

 with dark spots. 



9. Nemadactylus concinntjs. The fish so designated is stated bv 

 the author to be one of those species whose natural position is 

 difficult to ascertain, from their partaking of the characters of se- 

 veral different groups. Viewed as the type of a new genus, Nema- 

 dactylus may be characterised as having none of the bones of the 

 gill-cover armed or sculptured, the operculum itself being destitute
