Family Ocypodidae, 



Subfamily Macrophthalminae. Genus Macrophthalmus Latr., 1829. 



1.3. Macrophthalnius verreauxi H. M.-Edw., 1848. Alcock, iv. p. 377. 



Taken in Felidu Atoll, 30 f. 



14. Macrophthalmus latipes n. sp. (Fig. 114). 



Diagnosis, " A Macrophthalmus whose length is to its breadth as 5:8; with the front 

 very strongly bent down- 

 wards ; the upper edge of 

 the orbit slightly sinuous, 

 slanting so much backwards 

 that the sharp thorn at its 

 outer angle lies far behind 

 the level of the front ; no 

 stridulating organ ; the an- 

 tero-lateral edge with one 

 blunt tooth behind the orbital 

 angle and faint traces of 

 two mounds behind this 

 tooth ; eyes outreaching the 

 orbital angle by more than 

 a third of their length ; 

 chelipeds small, simple in 

 shape, with one blunt tooth 

 on the moveable finger and 

 no thorn on the inside of 

 the palm ; and walking legs 



with a spine near the end of the upper edge of the meropodites and long slender end- 

 joints, except in the case of the hindermost pair, where the last three joints are broad 

 and flattened." 



Length of only specimen (a male) : 5 ram. Breadth : 8 mm. Colour in spirit, white. In 

 the flattened shape of its last pair of legs, this species recalls the Portunid genus Fod- 

 ophthalmus, already curiously like Macrophthalmus in the length of its eyestalks and its broad 

 body. 



Dredged from 36 /. South Nilandu Atoll. 



Family Palicidae. Genus Palicus Philippi, 1838. 



1.5. Palicus jiikesi (White), 1847. Alcock, vi. p. 451. 



According to Alcock, " the Indian species of Palicus live among coral shingle at a depth 

 of from 10 to 40 fathoms, where their mottled coloration and granular rugose carapace 

 afford a good concealment." The majority of the specimens of this species taken by the 

 expedition were dredged on a bottom which contained coral shingle, but several were ob- 

 tained from foraminiferal mud, quite unlike and unmixed with coral shingle. The species was 

 taken from 25 to 45 fathoms in Suvadiva, Haddumati, South Nilandu, and Kolumadulu Atolls.
