The first, narrow like a neck, having on the upper portion 

 a short spine, and on the under surface a pair of appendages 

 or prolongations of two divisions or digitations. The 

 second is somewhat quadrilateral, with, on the middle 

 line of the back, two conical tubercles, and on the sides 

 two others, the upper pair the longer ; and having on the 

 under surface a pair of appendages of two digitations. 

 The third part is larger than the preceding, and has the 

 same tubercles and prolongations, and in addition, a small 

 spine on the superior portion, and in the mesial line of 

 the under surface. The fourth portion is rather the 

 largest, with two horns or tubercles on the upper surface, 

 a third on the median line of the under surface, and on 

 each side a long terminal prolongation, rather blunt. 

 Abdomen in form of a short tubercle in the centre of the 

 posterior part of thorax. Oviferous tubes very long, 

 slender, and twisted. Length, six lines and a half;

Character. Attached to their prey by means of two 

 long appendages which arise from the thorax. They 

 unite together either at the base or near the tip only, and 

 terminate there in a rounded knob like a button, by 

 means of which the animal maintains its hold of the part 

 to which it has attached itself. No thoracic feet, or they 

 are represented by these arm-shaped appendages. 



rr, anchor; and Kapiroc, arm.
