result being that their muscles are nearly parallel with the median line. The caudal 
stylets are situated far from each other, but close behind the posterior margin of the genital 
area. The whole area and its surroundings are naked. 
MALE. Unknown. 
OVISACS. Three oblong sacs have been found, their average length being like 
that of the female. 
LARVA. Unknown. 
POST-LARVAL DEVELOPMENT. A_ pupa densely covered with hairs all over 
is 22 mm. in length and -16 mm. in breadth. 
HABITAT. In the marsupium of a specimen of Gammaropsis melanops G. O. Sars, 
taken by the author in the harbour of Messina in May 1893, were found: one female, three 
ovisacs and one pupa. (The Rey. Th. R. R. Stebbing has kindly determined the host; he 
writes: »The specimen is imperfect, but appears to be Gammaropsis melanops G. O. Sars«). 
REMARKS. It must be supposed that the ovisacs were laid by the small female 
which was found together with them, and to which a spermatophore was attached, for the 
host is so small that the parasite must of necessity be small too. So it appears that in this 
respect this species is like S. vestita, but there is this difference, among others, that the 
trunk and the genital area are perfectly naked. 
7. Sphzronella chinensis n. sp. 
(Pl. II, fig. 6a—6f; pl. III, fig. 1a—1c.) 
FEMALE. The only specimen found (fig. 6a) was 1:01 mm. long and ‘88 mn. 
broad; the head a little above medium size, the trunk globular. The base of the maxillz 
and the part in front of the maxillipeds covered with hairs, as in the preceding species. 
The trunk rather scantily furnished with most peculiar membranous hairs, the base of which 
forms a very broad and flattened oval, and from this broad base the flattened hair increases 
somewhat in breadth, whereupon it is rounded off rather abruptly, which gives the whole 
hair almost the outline of an egg, the tapering end of which is cut off. The genital area 
has about the same shape as in S. vestifa, so it is longer compared with the breadth than in 
the other species, and forms a short oval, but the larger part of it is solidly chitinised ; the 
distance between the genital apertures is a little shorter than in S. vestita, but their form 
and direction are as in this species; the distance between the caudal stylets is of medium 
length and about equal to their distance from the area. The area is provided with mem- 
branous hairs, which in several places form a covering as close as the »scales« in S. vestita; 
finally, the surface extending from the area to somewhat beyond the caudal stylets is furnished 
with similar hairs; the greater part of these hairs are much narrower than those of the 
trunk and also different in shape, the hair in its proximal part being of equal width and 
then gradually tapering ends in a point.
