4. Clibanarius padavensis, de Man. 



C. padavensis de Man, Mergui Crnst. p. 242, pi. xvi. figs. 1-5 (1888); Hender- 

 son, Trans. Linn. Soc. 2 ser. Zool. Vol. V. pt. 10, p. 423 (1893). 



Pulicat, Madras Coast ; a large series. 



The largest specimen is an adult male measuring 70 mm. in length. 

 Young individuals are found in the shells of a Gerithium, older ones ia 

 the shells of Ranella, Eburna, etc., and on one of the shells there is 

 an encrusting hydroid. 



The second and third pairs of ambulatory legs exhibit a well-marked 

 longitudinal blue band, best seen on the posterior surface of the propodi. 

 This blue band is bordered both above and below, by a dark brownish 

 or reddish band. 



The species was first recorded by de Man from Mergui, and as 

 I have elsewhere shown, is common in the brackish back-waters, aloug 

 the Madras Coast, as far south as Tuticorin. 



Genus Eupagurus, Brandt. 



5. Eupagurus zebra, Henderson. 

 E. zebra, Henderson, Trans. Linn. Soc. 2 ser. Zool. Vol. V. pfc. 10, p. 425, pi. 

 xxxix. figs. 12-15 (1893). 



Station 175, off the east coast of Ceylon, depth 28 fathoms. Two 

 specimens in the shells of a Murex. 



The smaller specimen is a female with ova about 15 mm. long the 

 other a male about 20 mm. in length. 



The species was founded on two specimens, one from the Ceylon 

 coast, the other taken at a depth of 53 fathoms, off the north-west 

 coast of Australia. The latter, which was the larger of the two, measured 

 2L mm. in length. It is easily distinguished by its colour markings, 

 which take the form of dark red lines on the ambulatory legs, chelipeds, 

 carapace, and even on the antennal peduncles and flagella. From 

 evidence supplied by one of the original specimens, there is reason to 

 believe that this hermit-crab like the mollusc Avicula zebra, Reeve, lives 

 among hydroids, and the linear colour markings by their resemblance to 

 the ramuli of the hydroid, serve a protective function. 



6. * Eupagurus pergranulattis, n. sp. 



Station 175, off the east coast of Ceylon, depth 28 fathoms. An 

 adult female. 



The anterior portion of the carapace is membrauous, with the 

 median frontal projection slightly marked, and exceeded by the slightly
