pairs. The third maxillipeds in squamifera have the third 

 joint shorter than the fourth, in nexa 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 chelge, 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 magm'fica., 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 GalatJiea, 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 Bondeletii. Though the old naturalist 

 Rondelet well deserved honour, this was not the right 

 way to pay it. It may be noticed, however, that G. 0. 

 Sars, writing in 1889, speaks of Munida Rondeletii, Bell, 

 and Munida rugosa (Fabricius) as two distinct though
