398 Dr. A. Gtinther on new Species of Fishes. 



ment of the spinous dorsal, which corresponds to the thirteenth 

 scale of the lateral line. Dorsal spine moderately strong, the 

 length of the first being more than half the length of the head. 

 Caudal fin deeply eraarginate. Coloration uniform. 



Two specimens, 5 inches long, were collected by Mr. Gr. 

 Gulliver in fresh water in Rodriguez. 



Labrichthys celidota (Forst.). 



The specimens described by New-Zealand naturalists as 

 L. psittacula are not the Australian species so named by 

 Richardson ; they appear to me to be the adult of L. celidota^ 

 in which the dark lateral spot has disappeared or is disap- 

 pearing. The true L. psittacula has one and a half series of 

 scales between the lateral line and dorsal fin ; L. celidota two 

 and a half. 



Trochocopus unicolor. 



D. 14. A. ^. L, lat. 45. 



Eight longitudinal series of scales between the lateral line 

 and spinous dorsal. Snout rather obtuse, the small eye being 

 nearly in the middle of the length of the head. The height 

 of the body is a little more than the length of the head, and 

 one third of the total (without caudal) . The membrane behind 

 each dorsal spine deeply excised. Dorsal spines short and 

 stout. Coloration uniform brownish black. 



One specimen, 14| inches long, sent by Herr Darnel from 

 Sydney to the Godeffroy Museum. 



Bregmaceros punctatus. 



In a small collection of fishes from Cook's Strait, received 

 from Dr. Hector, I have found an example of the interesting 

 fish described by Capt. Hutton as Calloptilum punctatum 

 (Trans. N.Z. Inst. v. p. 267, pi. 11). I do not think that it 

 should be generically separated from B. Macclellandii — the 

 actual separation of the soft dorsal into two fins being evi- 

 dently an individual character, as in om* specimen the two 

 portions are connected by intermediate rudimentary rays. A 

 similar interruption, though much less perfect, can be seen also 

 in the anal fin. In the latter fin I count 57 rays, and in the 

 anterior portion of the dorsal 22, Capt. Hutton giving them 

 respectively as 44 and 11. The long isolated ray in front of 

 the anal, shown in the figure given by Capt. Hutton, is not 

 present in our specimen. I have also to add that minute teeth 

 are present in both jaws, and that the gill-membranes are 

 separate to the chin.
