menciug at the base of the tifth right leg-, it curves completely over the abdoiueu as far 

 as the base of the fifth left leg. 



Length of body in a male !) mm., right chclipede 12 mm., left chelipede lOo mm. A 

 female is about the same size. 



This small sjjecies comes nearest to C. Sharreri, A. Milne-Edw., common in deep 

 water off the east coast of the United States, Imt is distinguished at once from the 

 American form by its non-ciliated aml)ulatory (or perhaps swimming) dactyli and 

 propodi, and by its longer and more slender male organ. The only previovisly known 

 Indo-Pacific species is G. austndis, Henderson, from the Arafura Sea and Eiji, in which 

 the chelipedes are shorter and (]uite dilfcrently armed, with the ambulatory legs not 

 specially flattened.

This specimen is preserved in ilio same bottle with a Hydroid, Aglaophenia iirens, 

 Kirchenpaner, to which several examples of Avicula zebra, Eeeve, are attached, and 

 which have a similar coloration, so tliat the Mollusc and Crustacean probably live 

 together, and are protected by the similarity of their markings to the dai-k ramidi of the 

 Hydroid. In the British Museum there is a much larger specimen, taken by H.M.S. 

 ' Penguin,' on Holothuria Bank, N.W. Australia, a1 a depth of 53 fathoms, from which 

 the following description and also the figures are taken. 



The colour-markings of this very beautiful species are so striking as to distinguish it 

 at once from all other known si)ecies. Tliey take the form of dark blood-red parallel 

 lines along both surfaces of the two pairs of ambulatory legs, on the left or smaller 

 chelipede, on the merus and inner margin of the right chelipede, on the sides of the 

 anterior portion of the carapace, on the upper surface of the antennal peduncles, and as 

 a thin line, interrupted on each segment, along either side of the entire antennal tlagella. 

 The ocular cornea? are dark green, ami the contiguous portion of the eye-stalk is 

 encircled by a yellow band. The median frontal projection and the ophthalmic scales 



are yellow. 



The median fronttil projection is i)rominent and acute, reaching to alx)ut the middle of 

 the ophthalmic scales, which latter are small, sul)triangular, and entire. The eye-stalks 

 are long, and but little shorter tiian the antennal peduncles. The antennal acicle is 

 slender and slightly curved, reaching the level of tlu> end of llir eye-stalks. The
