Among several examples of Cirolana willeyi there occurred a 
single specimen undoubtedly belonging to the form figured and 
described by Schiodte and Meinert as Corallana nodosa , mas 
adultus. They describe and figure also the femina ovigera and 
the virgo, but Hansen suspects that two or possibly three species 
have been grouped together under one designation. A single 
specimen does not lend itself to the discussion of that question. 
So far as the male is concerned the superficial characters are very 
unmistakable. The projecting lobe of the first joint of the upper 
antennae attracts attention. The two little cephalic eminences 
between and slightly in advance of the eyes are indeed not shown 
in the figure which the collaborating authors supply, but they are 
well described in their text as a pair of short high carinae with short 
sharp apex. The nodules on the last three segments of the peraeon 
are, as they represent them, a large and small one close together 
on each side of the fifth and sixth segments, and on each side of 
the seventh a solitary large nodule. 
The eyes are large, distinctly facetted. 
The first joint of the upper antennae, so remarkable by its upward 
curved lobe, no doubt represents two joints in coalescence, the 
following much shorter and narrower joint being the true third 
joint of the peduncle. The flagellum in our specimen consisted 
of thirteen unequal joints, none elongate. The much longer 
second antennas had in one member of the pair a 17-jointed, in 
the other a 22-join ted, flagellum. 
The mandibles are elongate, differing greatly from those of 
Excorallana , both in the apical part and in the palp, this having 
not the first but the second joint longest, as in the other true 
Corallanidae. They agree in general structure with the mandibles 
of Tachcea crassipes , but the apical part, instead of being simple, 
has subsidiary teeth as in Alcirona . The spine-row is represented 
by a single spine. 
The lower lip has each division apically bilobed, the lobes being 
approximately equal and very slightly separated. 
The first maxillae agree in much with those of Tachcea crassipes 
but quite as well with those of Excorallana tricornis (Hansen). 
* On plate 1 b this species is named Tachcea nodosa by error.
