description and figures, based on one of Ljtingman's types. There 

 are in the PIETER FAURE collection two amphiurids which agree so 

 nearly with Koehler's figures and description that it seems to me 

 best to refer them to this species. The larger and better preserved 

 is 5 mm. across the disk and has arms about 20 mm. long. The 

 one particular in which these specimens do not agree with the type 

 is in the shape of the upper arm-spines. Koehler naturally lays 

 great stress on this feature for such flattened biscuit-shaped arm- 

 spines, as are shown in his figure, would certainly be a diagnostic 

 character of great value, if it were constant. But Ljungman does 

 not refer to it ; which indicates that it was either wanting in some 

 of his specimens (if he had more than one) or was not conspicuous 

 enough to attract his attention. In the two specimens before me 

 there is only a hint of this character ; in the larger specimen a 

 few of the uppermost spines near the base of the arm are flattened 

 and widened and one or two even show the biscuit-shape of Koeh- 

 ler's figure 16 to a trifling degree. The radial shields in the spe- 

 cimens before me are not quite so wide in proportion to their length 

 as in Koehler's figure, and the six primary plates of the disk are 

 more distinct. Under the circumstances however, in spite of these 

 differences, it seems to me better to refer these specimens to Ljung- 

 rnan's species than to give them a new name.

This is another of Ljungman's species which has not been met 

 with since its original description from a specimen, 4 mm. in disk- 

 diameter, from Mozambique. Verrill (1899) puts this species in 

 Amphipholis (although he says frankly that it has four oral papillae) 

 while gibbosus and integer he puts in Amphiodia. Ljungman however 

 distinctly says in each description, "Papillae orales quaternae", so 

 that until further material proves them to be otherwise unlike 

 Amphioplus, the three species must rest in that genus.
