a yellower tint (dark orange). The wings are coloured as in 
the female. 
The ventral segments are simple. In the antennz the 
last joint is moderately curved, narrowed to the apex, and 
obliquely truncated ; it is hardly as long as the penultimate 
joint. The intermediate joints, especially 7 and 8, are some- 
what flattened and dilated, widest in the middle of each joint 
(seen from above joints 7 and 8 are pentagonal). The third 
joint is about as long as the fourth and fifth together. 
The sides of the thorax near the insertion of the abdomen 
run out into conspicuous blunt and flittened (not spine-like) 
productions. In the tridentate apical ventral segment the 
middle spine is extremely long as compared with the two 
lateral ones, so that, without relaxing the insect and drawing 
this segment right out, one might almost mistake it for a 
Sphecius.

By R. Kirkpatrick, F.Z.8. 
[Plate XXXIII.] 
A small collection of Meduse made in the Inland Sea, 
Japan, by Mr. R. Gordon Smith was sent by him to 
the Natural History Museum. The specimens, eight in 
number, represent three genera and species; of these, one 
genus and one species have not hitherto been described. 
‘The following is a list of the species :— 
LEPTOMEDUSE: Gonomeandrus chrysostephanus, gen, et 
sp. 0. 
TRACHOMEDUSE: Gonionemus Agassizii, Murbach and 
Shearer. 
Discomepus#: Aurelia aurita, Linn., var. japonica, 
Kishinouye. 
LEPTOMEDUS4. 
Family Cannotide, Haeckel. 
Subfamily Pozrorcurpaz, A. Agassiz. 
GONOMEANDRUS*, gen. nov. 
Polyorchide with four radial canals, each with an un- 
branched transversely meandrine proximal portion, situated on 
a gastric peduncle, and with a pinnately branched distal 
portion on the wall of the subumbrella, the branches ending
