fourth pair a little backward. The cephalic part of the cephalo- 
thoracie segment shows nearly a triangular shape; in the middle 
it bears the oculiferous tuberele. This is a great deal more elevate 
and much more acutely-pointed with the young specimen than with 
the adult speeimens. Sabine (l.c.) says, that he observed two eyes 
and even supposes that there are indeed four of them — but I think 
this is an error, for I quite agree with Jarzynsky who says 
the eyes are deficient. The abdomen is long; it is a little bent 
over and thus it shows a curved shape, and as is the case with 
the other species of the genus Colossendeis it is connected with 
the thorax by means of an articulalion. The extremely charac- 
teristic shape of the proboseis is easily seen from the figure. 
The mouth is triangular and very large; it can be closed in 
some degree by the three labial-formed slips at the interior. 'The 
middle and dorsal part of the proboseis sligtly overhangs the mouth 
and the whole proboseis is a litte bent over to the ventral side. 
Body, proboseis and legs are almost absolutely smooth — only when 
using a strong magnifying glass small spines are observed on some 
of the joints of the leg. The palpi are long. The first two joints 
are extremely small, the third is the longest and considerably lon- 
ger than the fifth; the fourth is very short, the sixth only little 
longer; the seventh is about twice as long as the sixth and the 
three last joints are of the same length as the sixth. Small hairs 
are seen on the four last joints. 
Of the ovigerous legs the first three joints are very small, the 
fourth and the sixth (of which the latter is a little longer than the 
first) are the longest of all and of about the same length as the third 
joint of the palpi. The fifth joint has about one third the length 
of the sixth; the four last joints are nearly of the same length; a 
distinet but not very long claw finishes the leg. Of the so-called 
denticulate spines of the four last joints I have given a drawing in Fig. 
42. As is the rule with the species of this genus, these spines are 
placed in different rows, those of the one side being a great deal 
longer than those of the other side. Fig. 42 shows all the spines 
present on the 8th joint of the leg; they are long-conical but their
