liaving the oral aperture contracted at the side, with the part 

 below the contraction narrower than tlie part above. At each 

 side of the oral aperture there is a small, raised, rounded avi- 

 culariuni, and any of these may be replaced by a large 

 spathulate one, in one case both avicularia being- thus re- 

 ])laced. Usually the spathulate avicularia are directed 

 distal ly, but one is diagonal, or it may be directed proxi- 

 mally. The bar to the avicularium has a small central 

 denticle. 



The granular ovicell is globular, widely open, so that the 

 operculum cannot close the ovicell aperture. At the bifur- 

 cation there is a large round opening with a raised border 

 (tig. 3), the object of the opening is not clear. It might 

 have been for a large avicularium, or for a radicle, but the 

 position does not make this jjrobable. 



It is much like the fossil Characodoma halli, Maplestone *, 

 from Mornington and Mitchell River, Victoria, Australia, 

 which, however, has the quadrate zoarium articulated, and 

 the ovicelligerous zooecia are surrounded by irregular nodules ; 

 however, the shape of the zooecia is the same with the ovicell 

 in the same position, but in C. halli there are small triangular 

 or spathulate avicularia replacing the semicircular or spathu- 

 late ones of L. hifurcata.

This does not appear to be uncommon at Naples, and 

 Kirchenpauer left a manuscript description in the Zoological 

 Station, calling it Lepralia dolirni. When the manuscript 

 was shown to me, it was my intention to describe and figure 

 tiie species, using the name given by Kirchenpauer, and I 

 have sent away some specimens exjjlaiuing that Kirchenpauer 

 had given it this manuscript name.
