Plate LXX. Figure 9. 



A small rudely spinulose species covered with adhering dirt 

 Body elliptical of moderate width, abdomen small. Proboscis large, 

 fusiform, much swollen in the middle, 

 large at the distal end, longer than half 

 the length of the body. Eye-tubercle 

 rather large, subclavate, with a rather 

 lai'ge, brown, 4-lobed eye-spot at the 

 rounded tip. Legs crooked, covered with 

 rough spinules; 3 basal joints short; 4th 

 and 5th longer, a little swollen; 6th 

 longer and more slender ; Yth very short; 

 8th strongly curved ; dactylus strong and 

 much curved ; two accessory claws and 

 several smaller spinules. Palpi long and 

 slender, tapered, extending much beyond 

 proboscis, 10-jointed ; 1st and 3d joints 

 short; 2d and 4th long; last 6 subequal, 

 very well defined, rather short ; the four 

 last fusiform, the terminal one a little 

 the longer and thinner. Antennae nearly 

 as long as the proboscis, 3-jointed, spinu- 

 lose, two basal joints long, 2d stouter, clavate; dactylus very small, 

 forming a very small chela. Accessory legs nearly concealed by 

 several clusters of eggs, 9-jointed, 2 basals and 3 terminals very 

 short; 3-6 longer. Length of body and proboscis 2™"" ; of proboscis 

 0.75'"". 



One specimen, Bailey Bay, low-tide. 



This species differs from typical Ammothea in having the palpi 

 10-jointed instead of 8-jointed. The number of joints in the accessory 

 legs was not made out very clearly, but 9 joints were visible.
