FAMILY SYNGNATHID^E. 



Genus HIPPOCAMPUS, Rafinesque. 



HIPPOCAMPUS ABDOMINALIS, Lesson. 



Hippocampus abdominalis (Lesson), McCulloch, Zool. Results 

 " Endeavour," i., pt, i., 1911, p. 29, pi. vi., fig. 1. 



Hippocampus graciliformis, McCulloch, Loc. cit,, fig. 2. 



Two specimens, 110-120 mm. long, though more like 

 H. abdominalis form than that of H. graciUformis, nevertheless 

 leave no doubt that the latter is but the young of the former. 

 The form of the coronet and cephalic spines is intermediate 

 between the two as is the development of the tubercles, and to 

 a lesser degree, the breadth of the abdomen. The length of the 

 snout is different in both specimens. They are pure white in 

 formalin with chocolate-brown spots and crossbars, which vary 

 greatly in their arrangement ; the dorsal fin has a rather broad 

 dark edge.

FAMILY STROMATEID^E. 

 Genus HYPEROGLYPHE, G'ttnther. 



Hyperoglyphe, Giiuther, Brit. Mus. Cat. Fish., i., 1859, p. 337 

 (Diagramma porosa, Richardson). 



Eurumetopos, Morton, Proc. Roy. Soc. Tasm., 1887 (1888), 

 p. 77. Id,, Waite, Trans. N. Zeal. Inst , xliv., 1912, 

 p. 202 (E. johnstonii, Morton). 



Regan 1 regarded Hyperoglyphe as a synonym of Leirus, Lowe, 

 but it seems to be separable from that genus by the constant form 

 of its first dorsal fin, of which the spines are very strong, and the 

 median ones are higher than those following them. 



In his definition of Hyperoglyphe, Giinther has described the 

 teeth as arranged in villiform bands on the jaws, but they really 

 form single rows as noted by Richardson in the original descrip- 

 tion of H. porosa. 



Eurumetopos, Morton, is evidently the adult form of 

 Hyperoglyphe. 1 have compared my examples of E. johnstonii 

 with Richardson's description and figure of H. porosa, and find 

 no important differences between them. Though all are of large
