 Iphione ovata. 



Iphione ovata, Kinberg, Oefvers Vet-Akad Forh., 1855, p. 383, 

 and Fregat. Eugen. Resa, p. 8, tab. iii., figs. 8, 8a — 8e ; Quatre- 

 fages, 1. c, p. 269 ; Baird, 1. c, p. 181. 



Antennse and cirri ciliated, cylindrical, with a long attenuated 

 apex ; bases of the antennfe longer than the cephalic lobe ; 

 antennae shorter than their bases and the cephalic lobe ; elytra 

 free from cilia on the margin. Body 12 mm. in length and 7 in 

 breadth, convex above, robust. Eyes placed in the postero- 

 external part of the cephalic lobe ; buccal cirri long, half the 

 length of the palpi. Elytra reticulate, the areolets in turn with 

 hexagonal reticulations, obliquely reniform, the outer part broader, 

 minutely tuberculous. Feet uniramous, the dorsal and ventral 

 setse of the same length. Dorsal cirri short, scarcely longer than 

 the setse, cylindrical with a long subulate apex; ventral cirri 

 styliform, reaching the apex of the feet, sparsely ciliated. 



A species of Iphione very common on coral reefs on the coast 

 of Queensland is seemingly the /. ovata of Kinberg. There are 

 a few points of discrepancy between my specimens and the 

 descriptions and figures in the '* Voyage of the Eugenie," but they 

 are not of great importance. Thus the thin terminal portion of 

 the outer peristomial tentacles is not nearly so long in my 

 specimens as in Kinberg's figure, and the reticulations on the 

 scales (which are formed of beaded lines) are not nearly so large. 

 I obtained specimens of this species from Port Curtis, Port 

 Molle, Port Denison, and Thursday Island. It was found at 

 Honolulu during the voyage of the Eugenie. 



The dorsal tubercles in this species are transversely elongated, 

 and the integument covering them is thin and transparent. The 

 mouth leads into an eversible oesophagus, the walls of which in
