176 A HISTORY OF RECENT CRUSTACEA 
pairs. The third maxillipeds in squamifera have the third 
joint shorter than the fourth, in newa equal to it, in dis- 
persa longer than it. By this simple combination all the 
five species are neatly distinguished. The sexes of Gala- 
thea often show a considerable difference in the chelipeds, 
those of the male being the longer. In Galathea squami- 
fera, the two last joints of the chelipeds in the female 
touch all along the inner margins of the chele, whereas in 
the male they stand apart, and have a peculiar curvature, 
meeting only at the apices. ‘This is so pronounced a 
feature that it misled Spence Bate into establishing a 
separate species, which he called digiti-distans, meaning 
‘with the fingers wide apart.’ Galathea magnifica, Has- 
well, an Australian species, only half an inch long, ap- 
pears to make up for diminutive size by its striking 
appearance. ‘The description of it says, ‘Colour bright 
red, with a brilliant purple stripe down the centre of the 
carapace ; legs ornamented with transverse bands of 
darker red and purple; fingers dark reddish brown, yellow 
at the tips.’ 
Munida, Leach, 1820, nearly resembles Galathea, but 
is distinguished by having a slender stiliform rostrum, and 
the supraorbital spine on each side of its base not small 
but well developed. Moreover, in general, the carapace 
has a spinulose surface, and its cardiac region distinct, 
and the pleon has one or more segments with a series of 
spinules on the anterior dorsal margin. The chelipeds 
and walking-legs are elongate and slender. ‘The type 
species Munida rugosa (Fabricius, 1775) is distributed over 
all the seas of Europe. The very long chelipeds make it 
conspicuous. ‘The third maxillipeds have the third joint 
longer than the fourth. The chelipeds and ambulatory 
legs are without epipods. It is not to be met with in 
shallow waters. Bell, on insufficient grounds, altered the 
name to Munida Kondeletii. Though the old naturalist 
Rondelet well deserved honour, this was not the right 
way to pay it. It may be noticed, however, that G. O. 
Sars, writing In 1889, speaks of Munida Rondeletii, Bell, 
and Munida rugosa (Fabricius) as two distinct though
