than the fourth. No orhital rim. Skin entirely smooth, without 

 tubercles or tentacles. Four ocellated spots, about as large as the 

 eye, and the anterior equidistant from each other, along the upper 

 half of the body. Fins indistinctly reticulated with brown, some of 

 the reticulations being distinct rings. 

 South Australia. 



Myxus leuciscus. (Plate LXV. fig. A.) 



D. 4J|. A. jg. L. lat. 47. L. transv. 14. 



Teeth small, movable, bent, those of the upper jaw in a single 

 series ; a deep notch in the middle of the upper jaw to receive the 

 mandibulary symphysis. Lower jaw with a similar series of hori- 

 zontal teeth ; other smaller teeth appear to be destined to replace 

 those in function. Lower surface of the mandible without transverse 

 folds. Palate apparently toothless. The maxillary does not quite 

 extend to the front margin of the eye; Snout pointed and rather 

 longer than the eye, which is one fourth of the length of the head, 

 and only two thirds of the width of the interorbital space. The 

 depth of the body is scarcely more than the length of the head, 

 which is one fourth of the total length (without caudal). Pectoral 

 extending to the commencement of the spinous dorsal, which corre- 

 sponds to the fifteenth scale of the lateral line. Dorsal spines rather 

 feeble, the first, which is the longest, being not quite half as long as 

 the head. Caudal fin emarginate. Coloration uniform, back greenish. 



One specimen, 5| inches long (no. 273), from the Godeffroy 

 Museum ; it was obtained at Rarotonga, Cook's Islands. 



Chilinus godeffroyi. (Plate LXVI.) 

 D.4 A. S. L. lat. 21. 



The height of the body is nearly equal to the length of the head, 

 and two fifths of the total (without caudal). Head longer than 

 high ; snout compressed, rather pointed, its length being two fifths 

 of that of the head. Chin not prominent. Scales on the cheek in 

 two series, the lower of which is composed of three or four scales, 

 and does not extend on to the praeopercular limb. Caudal fin 

 rounded. Tubules of the lateral line simple. Most of the scales 

 with a well-defined deep-brown vertical streak ; two parallel brown 

 lines across the prseorbital, two other similar lines behind, and one 

 above, the eye. Vertical fins with brown reticulations ; a white spot 

 on the base of the last dorsal and anal rays. 



One specimen, 5| inches long (no. 440), from the Godeffroy 

 Museum ; it is from the Tonga Islands. 



Platyglossus nigromaculatus. (Plate LXV. fig. B.) 

 D. J. A. J. L. lat. 28. 



The height of the body is one third of the total length (without 

 caudal), and a little more than the length of the head. Snout 

 pointed, somewhat longer than the eye, which is two ninths of the
