eyes are placed in a square, the anterior clusters rather more ap- 

 proximated than the posterior : body of 4 transverse segments, each 

 armed with a dorsal tubercle along the medial line, and 1 an obtuse 

 one on each side, within which there is a round depression ; the pos- 

 terior margin of the segments elevated, the fourth narrower, obcor- 

 date, its tubercle placed forward, while behind it is terminated by 

 the narrow cylindrical abdomen : legs 4 pairs, the first and second 

 rather longer than the third, and the fourth are still shorter, all of 

 them with 8 joints nodulous at the knees ; the three basal (coocaz) 

 short, sub-equal, the fourth and fifth twice as long, with two unequal 

 tubercles on the distal ends and a bulged process underneath, sixth 

 joint shorter than the fifth, seventh minute, globular, eighth curved, 

 as long as the sixth, and terminated with a sharp claw, — the joints 

 forming the tarsus covered with a very short hairiness on the under 

 surface. 



The female appears to be rare. She carries her innumerable ova, 

 enveloped in a broad square gelatinous membrane or apron, under 

 the body between the legs, where they are attached in front to a 

 pair of filiform jointed organs, which originate from a callous ring 

 that encircles the base of the rostrum. The joints are 10, the 5 ba- 

 sal ones shorter than the others, while the terminal one forms a 

 slightly curved sharp claw. — Linnaeus describes the rostrum as be- 

 ing of the length of the feet — " rostrum membranceum, subsubula- 

 tum, longitudine pedum," — which, if not an error, might seem to in- 

 dicate another species.

Description. — " Body linear : snout long, cylindric deflected : 

 no feelers : eyes four, fixed in a conical tubercle on the top of the 

 fore part of the body behind the snout, placed two forward, two 

 backward, and appear under a microscope strongly reticulated ; the
