78 G. M. PITTOCK ON FLOSCULARIA TRIFIDLOBATA. 



More careful examination, however, showed that it has five lobes, 

 of which the dorsal one is long, pointed, and trifid at the apex, 

 and crowned with three brushes of short setse. The other lobes are 

 small, being little more than slight projections of the coronal 

 rim, and not quite equi-distant from each other, and each crowned 

 with a brush of short setse. The two ventral lobes are close 

 together, and the lateral lobes close to the base of the larger 

 dorsal lobe, leaving a wider space than usual between the lateral 

 and ventral lobes. The setse are not continuous round the coronal 

 rim. 



Three very small antennas can be made out, one dorsal and two 

 lateral, and the space between the integument is filled with 

 numerous brown granules. 



Before attempting to describe or to name this floscule, I first 

 submitted it to Mr. Rousselet, Mr. Western, and Mr. Hood of 

 Dundee, all of whom pronounced it to be specifically distinct from 

 any other known floscule, and especially differentiated by the 

 trifid character of the dorsal lobe, which suggested the name 

 trifidlobata. 



Spec. Char. — Lobes five, the dorsal one long, pointed, trifid 

 at apex, crowned with three brushes of short setse, the other 

 lobes small and inconspicuous, without knobs ; not quite equi- 

 distant round coronal disc, each with a brush of short setas. 

 Tube small and sometimes indistinct, antennas three, each with 

 tuft of short setse. Jaws as in other floscules. Eyes absent. 

 Length : total JL, of body T |_, foot twice the length of body.
