PHOLOE MINUTA. 437 



the body; posteriorly a pair on each segment. First foot with two tentacular cirri; 

 without bristles. Dorsal lobe of the foot with slender, tapering, spinous bristles. 

 Inferior division with stout, falcate, compound bristles. Nerve-cords forming triangular 

 flattened areas in section on each side of the median line, the oblique muscles passing to 

 their insertion above them. 



De Quatrefages (1865) gave the group three "antennae," a facial tubercle, and two 

 tentacles, the upper of which was bifid. Alternate scales anteriorly, while posteriorly 

 all the segments had scales. No dorsal cirri. He thus had an imperfect acquaintance 

 with the genus. Grrube's account 1 was more accurate. 



Pholoe minuta, 0. Fabricius, 1780. 



Specific Characters. — Head somewhat rounded, bearing a short subulate median 

 tentacle, with a few papilhe on its surface. Two eyes on each side — connate, the 

 anterior being the larger. There are two short tentacular cirri, also with a few small 

 papillas on their surface. Two prominent papillae project behind the eyes, and sometimes 

 overlap them. The palpi are somewhat massive, short, tapering organs, with a smooth 

 surface. Body small, forty-five to seventy segments, and about three-quarters of an inch 

 long as a maximum. It -has two slender styles posteriorly. Scales ovate or reniform, 

 with a series of cilia having moniiiform tips along the outer border, and more sparsely 

 along the posterior border; while the surface, especially at the inner region, is areolated. 

 Dorsal lobe of the foot forms a prominent process with a convex margin externally for 

 the dense tuft of bristles, which are slender, tapering, and spinous. Yentral lobe an 

 oblique cone with numerous papillas over the surface. The shafts of the bristles are 

 stout, the distal convexity having numerous spikes. The terminal piece is short and 

 falcate, and the edge is generally spinous. The ventral cirrus is short and tapering.
