LEODICID^ OF THE WEST INDIAN REGION. 93 



unpaired has 7. There are small plates with inrolled edges lateral to the outer paired 

 plates. The mandible (text-figure 332) is slender, its beveled edges colored a dark brown. 

 Webster gave no data as to the locaUty of his specimen. I found it abundant in 

 Bermuda, in Montego Bay, Jamaica, and in Tobago, wherever there is decaying coral 

 rock, as in the porous surface layer bored by sponges. It is abundant in the Tortugas 

 in similar localities and it occurred in bottom rock dredged at 6 fathoms. It was 

 found also in collections from Guanica Harbor and from Guayanilla Harbor in Porto 

 Rico. At the Tortugas some were collected in sponges. A female collected in the 

 Tortugas June 17, 1913, seemed to be nearly mature.
