lent by Dr. Koenike. In the Irish examples the inner corner 
of the third palp-sezment is rather well developed, with from 
12 to 14 short stout spines, none of which are feathered.

1899. Zool. Anzeiger, Bd. xxii. p. 67, fig. 8. 
The type form of this species occurs but rarely ; the preva- 
lent form found here should, I think, be referred to a distinct 
race or variety of L. Soarz. 
anstabilis, var. Nn. 
My specimens of this variety agree in size with those 
described by Dr. Piersig, ranging from 3 to 4 millim. in 
length ; yet the eye-plate and palps are uniformly larger, and 
there are other differences in structure. 
The eye-plate (figs. 4 and 5) measures from *45 to "48 
millim. across, length of capsule about 25 millim., of more

robust structure than in the type. Bridge somewhat longer 
and broader, with the posterior emargination either round or 
more or less sharply angled. 
The capitulum measures about ‘66 millim. from the front 
margin of the maxillary plate to end of pharynx ; the type of 
structure greatly resembles that of HH. Jiilleri, Koenike 
(Deutschl. Hydrach. pl. xlvii. fig. 1538 ¢@). The palps are 
robustly built, length about 1°20 millim. Inner corner of 
third segment well developed, with from 14 to 18 short stout 
spines, the innermost ones weakly feathered. Fourth seg- 
ment strongly swollen on the inner margin, near which 
there are about 6 long spines, and the usual group of 4 or 5 
strongly feathered spines close to the distal margin.
