inner aspect (fig. 12). ‘The female as seen from the side is moderately 
and evenly rounded on the dorsal aspect and somewhat flattened below, 
as shown in figure 13. 
The antennules appear to be four-jointed, but the end joint is very 
small, while the penultimate joint is nearly as long as the preceding two 
joints taken together (fig. 14). 
The second maxillipeds are moderately large and composed of four 
joints ; the first and second joints are robust, and the second is consider- 
ably more elongate than the next two joints combined, which are short 
and narrow, and furnished with a short terminal claw (fig. 15). This 
form does not agree with any species known to me. No males were 
observed. | Sr 
(2) Spheeronella sp. from a Hemilamprops rosea (Norman). 
_A moderately large Spheronella, bright red in colour, was quite. 
recently obtained in the marsupium of a specimen of Hemilamprops rosea 
(Norm.) captured in Loch Fyne by Dr. Williamson. So far as I am 
aware no Chontostomaton has yet been recorded from this species of the 
Lampropide.

A male specimen of this species was obtained in some material dredged 
off St. Monans on May 22,1901. The species appears to be widely 
distributed, but moderately rare. The late Dr. Robertson has recorded 
this species from the Firth of Clyde, and I have observed one or two 
specimens in gatherings dredged off Fair Island in October, 1900.
