/i 1 marks. The forms belonging to this family exhibit several apparently 

 very anomalous character-, e-pecially as regards tin- uvneral form of the body, 

 the structure of the 1st pair of legs, and the composition of the genital apparatus. 

 Yet in the structure of the greater nnmher of the appendages, they seem to come 

 nearest to the /'///'</////. \\\ spite of the very dis-imilar external appearance of 

 the body. Two nearly-related genera of this family are represented in the Nor-
