Bryozoa of the Bay of Naples. 
fore Smitt is not followed, though Legentilii is an earlier 
name than reticulata. 
In some cases the peristome is very much raised, in others 
only slightly so, as figured ; the ovicells are perforated, not 
very much raised and rather behind the peristome ; the pecu¬ 
liar feature is the position of the avicularian mandible, which 
is much below the aperture, and often very long and projecting 
into the aperture of the cell below, when it is frequently bifid; 
and from this division, which reminds me of a serpent’s 
tongue, it may be called var. ophidiana if there is any occa¬ 
sion to distinguish it. This is not the only case of the point 
of the mandible appearing divided, as it is sometimes so in 
Eschara verrucosa. Although the mandible is placed so low 
down, the avicularian chamber is immediately below the 
aperture, and the two pores just below the mouth open into 
this avicularian chamber. 
Sometimes it is incrusting, at others partially free, so that 
to those who recognize the genus Hemeschara it would belong 
to it; but, following Smitt, I should call the two forms 
stadium Lepralia and stadium llcmeschara. 
The operculum (26*) is subsemicircular, the lower margin 
slightly curved inwards, 0T9 millim. wide, 0T44 long. 
Muscular impression close to the border, about O'OS from the 
proximal edge. 
Inside the oral aperture there is a wide denticle. 
There are three distal and six lateral rosette-plates. The 
distal plates are situated close to the basal walls. 
L. reticulata has been found from the Arctic Ocean to New 
Zealand.

The cells are ovate-elongate, punctured specially near the 
edges ; internal denticle; but instead of having a single sub¬ 
oral avicularium, there is usually one on each side; some¬ 
times one of these is very large, covering nearly the whole of 
the cell, with the other extremely minute. The peristome is 
considerably raised.
