LEODICID.E OF THE WEST INDIAN EEGION. 



Each winged seta has two flattened expansions, set at an angle with each other, the 

 whole marked with many diagonally arranged striations. In many the apex was much 

 more elongated than in the specimen figured. The hooded setse have 4 or 5 small 

 teeth dorsal to the large tooth. 



The maxilla (text-figure 355) is dark brown in color, the carrier very dark, but with 

 a lighter margin. The basal portion of the forceps is rather broad and long, extending 

 for more than half the length, while the terminal portion is slender and curved. This 

 terminal portion is much darker than the basal. The proximal paired plates have 5 

 large teeth on either side, the latter dark brown, while the remainder of the plates are 

 much lighter. Of the two pairs of distal paired plates, the inner have 3 and the outer 

 have 2 teeth. Each is continued laterally into a chitinous plate dotted with black. In 

 the figure the plates on the left side are inverted in order to show these continuations. 



The mandible (text-figure 356) is very delicate and transparent and difficult to 

 separate from the maxilla. The only marked trace of color is a small patch of pigment 

 on the outer anterior angle, the concentric lines being marked only very faintly with 

 yellow. The separation of the beveled portion into two halves is not as complete as 

 in other forms, the lines extending completely across from one side to the other. The 

 mandible figured was from a Bermuda specimen, the maxilla from one collected in the 

 Tortugas.

The first collection of L. cingulata was in dreclgings about 12 miles south of Logger- 

 head Key, the animals living in fine crevices in the bits of broken coral which cover the 

 bottom in some localities. In Bermuda I found them common in the crevices in the 

 decayed surface of the coral rocks at about low-tide mark, living in association with 

 Nicidion kinbergii. One was taken in Tuckerstown Bay, in a bit of hollow plant stem 

 lying in the mud. A few were found on Buccoo Reef, Tobago, and in Montego Bay, 

 Jamaica.
