Lestidium nudum, Gilbert. Bull. U.S. Fish Comm., xxiii, 1905, p. 607, 

 fig. 236. 



This fish was previously known only from the type specimen, taken 

 in the Hawaiian Islands ; it Avas obtained in the trawl, operating at a 

 depth of 283 to 284 fathoms, but Dr. Gilbert thinks it may have been 

 captured near the surface. It measures 200 mm. in length, and is fully 

 described and figured. 



Mr. Oliver has placed three specimens of this interesting species in my 

 hands. They were washed on to Denham Bay beach, on Sunday Island, 

 in July last year, and are in very good condition. They have the appear- 

 ance of immaturity, no colour-markings being developed ; they are smaller 

 than the type, being respectively 129 mm., 109 mm., and 105 mm. in length. 



The radial formulse, in the order given, is as follows : D. 12, 10, 10 ; 

 A. 29, 31, 32. The other fin-rays are as in the type, and in every case the 

 scales in the lateral line number 68. 



Gonorhynchus gonorynchus, Linn. 



Several small examples are included in the collection ; they were washed 

 up on to the beaches, and are all similar to the young ones I have previously 

 described,* which therefore represent the normal coloration of immature 

 specimens. A large example, taken in this province, and preserved in the 

 Museum, measures 384 mm. in length. 



Congrellus, sp. 



Several small Leptocephalid eels are recognised as of this genus, but 

 it is not possible to identify them specifically. There are also a number 

 of larval forms, possibly of different genera, entered in the comparative 

 list as.: Atnpichthi/s. 



Mursenichthys oliveri, sp. nov. Plate XXXV, fig. 2. 



Head acute, 11-5 in the total length ; anterior nostril in a tube close 

 to the lip, and just above the tip of the mandible ; posterior nostril a largo 

 pore, midway between the anterior one and the angle of the mouth, also 

 close to the lip ; cleft of mouth one-fifth the length of the head, extending 

 posterior to the eye ; the latter small, 3-3 in the length of the snout. Gill- 

 opening very small, a vertical slit, subventral in position. Teeth in the 

 jaws, on the vomer and palatines. A row of large pores along the margin 

 of the upper lip and another from the snout passing over and behind each 

 eye ; a transverse series of 5 pores across the upper anterior half of the 

 head ; the lowest pore on each side forms the first of the lateral series, which 

 to the number of 135 passes along the middle of the side to within a head- 

 length of the caudal ; this series is arched on the head, and there are 67 

 pores anterior to the vent. Head and body together a little shorter than 

 the tail. Body worm-like, its depth about Jg- the total ; tail not com- 

 pressed. Dorsal fin low, arising exactly in the middle of the length and :\ 

 short distance posterior to the vent ; anal similar to and arising slightly 

 in front of the dorsal, and uniting with it round the end of the tail. 



Colours. — Olive-brown above, the tint formed of closely placed spots, 

 which are more widely spaced on the sides ; lower parts immaculate. 



Length of specimen, 207 mm.
