AGASSIZ AND MAYER: ACALEPHS FROM THE FIJI ISLANDS. 177 
Beroë australis, nov. sp. 
Plate 16, Figs. 49, 50. 
The animal is 40 mm. in length, and the body is compressed laterally, one 
side being about three times as broad as the other. Our figure exhibits the 
broad side. The aboral otocyst is surrounded by a figure 8-shaped row of 
branched papillæ. The long axis of this row lies in the plane of the broad 
side of the Ctenophore. There are 8 rows of ciliated plates that are bordered 
by masses of stellate pigment cells (see Fig. 50). Fight radial canals run be- 
neath the ciliated plates, and in addition to these there are two wide, straight 
lateral tubes (l., Fig. 49). All of these tubes communicate with the circular 
canal (c., Fig. 49) ; and are also put into further communication, one with an- 
other, by means of a simple network of connecting tubes (k., k., Fig. 49). The 
month opening is very wide and deep. The pigment cells of the ciliated plates, 
and of the papille surrounding the aboral sense organ, are erimson-lake in 
color. The gelatinous substance of the animal is quite transparent. 
Many specimens of this Ctenophore were found in Suva Harbor in December. 
The animal swims with remarkable rapidity by means of the movements of its 
combs of cilia.

Several specimens of this Siphonophore were captured by us among the 
Fiji Islands. It is well represented by Lesson’s figure.
