56 LEODICID^ OF THE WEST INDIAN REGION. 



basal joints, the terminal joints rather small, with apical and subapical teeth covered 

 by a hood with smooth margins. The pectinate setae (text-figure 179) are relatively 

 large, with about twenty teeth, of which the terminal ones are largest. A dorsal acicula 

 from a gilled somite (text-figure 181) has a blunt apex and is dark-colored until at the 

 very apex. The hooded ventral acicula (text-figure 180) is smaller than the dorsal and 

 is colored like it, but has a subapical tooth and a hood. 



The maxilla (text-figure 182) has a small carrier, the forceps long and not much 

 curved. The proximal paired plates have each 3 large teeth, the unpaired has 6, the 

 right distal paired has 6, the left has two large and 2 small ones. The proximal 

 paired plates are lighter in color than the distal ones or the forceps. There are small 

 accessory plates at the sides, and crescentic colored patches distal to the plates. The 

 mandible (text-figure 183) is small, with slender halves united only at a point. The 

 general color is brown, but the halves are darker at the distal end, especially at the ends 

 of the concentric lines.
