STALK-EYED CRUSTACEA 



equal size ; the fifth is much smaller ; all the teeth are granulous on their an- 

 terior border, smooth on their posterior border ; the depressions between the 

 third and fourth and the fourth and fifth teeth are continued in as furrows 

 for some distance on the carapace^ finally uniting and meeting the cervical 

 furrow. The upper margin of the orbit forms a tooth at the inner angle 

 above and outside of the external marginal tooth of the front ; there is a 

 closed fissure near the middle of the superior orbital border; the external 

 fissure is a triangular notch ; a blunt tooth at the" inner angle of the lower 

 margin. There is no subhepatic tubercle. A transverse row of tubercles on 

 the front of the eye-stalk (when viewed retracted within the orbit) just inside 

 the eye. Chelipeds unsymmetrical ; carpus squamoso-rugose, with a slight 

 transverse groove, and armed with a prominent but not very sharp internal 

 tooth; propodus stout, superior border rounded and squamoso-tuberculate, 

 outer surface smooth ; fingers of larger chela gaping, movable finger armed 

 with a large blunt tooth at base ; fingers of smaller chela slenderer, without 

 prominent teeth ; fingers of both hands black, hooked at extremities, tips 

 crossing. Upper edge of merus of ambulatory appendages lightly denticu- 

 lated, excepting the posterior pair. Base of abdomen entirely covers the 

 sternal segments; penultimate segment of abdomen short, posterior angles 

 prolonged backward; last segment short, pentagonal. In young specimens 

 the granules of the carpus and propodus are more numerous and sharper-

S. L Smith in 1869.

either by Stimpson or A. Milne Edwards. The type of the genus, Micropan- 

 ope scidpUpes Stimps. (~ M. pitgilalor A. M. Edw.), does not seem to belong 

 to the same assemblage of species as Panopeus tannery which differs from the 

 typical species of Panopeus merely by the granulation of the carapace and 

 the serration of the meri of some of the ambulatory appendages. These pecul- 

 iarities do not, in my opinion, justify the separation of P. ianneri from the 



genus Panopeus.
