what irregular and wedge-shaped, the outer edge being flattened, those 
towards the centre a little shorter; these are frequently followed by a small 
rounded one, which is sometimes wanting; the last one is short and rounded. 
The narrow space between the mouth-papille and mouth-shields is covered 
with small rounded granules, except about opposite the first, where the side 
shields are partly exposed. The teeth have been much injured, but there 
appear to be five, which are stout, broad, the lower ones somewhat squarish, 
with rounded angles when seen from above, the end flattened, or wedge- 
shaped, truncate or bevelled. The arms are well rounded, stout at base, 
regularly tapering to the ends, but not becoming slender. Under arm-plates 
eight-sided, slightly overlapping, the first eight or ten broader than long, 
followed by a number that are as long as broad, the length gradually in- 
creasing, so that at the twenty-fifth plate the length is decidedly greater 
than the breadth. Inner tentacle scales oblong, shorter than the arm-plates, 
toward the disk very broad and stout, truncate, farther out gradually becom- 
ing more slender and pointed; outer tentacle scale very short and broad, 
about half as long as the inner; those at the base of the arms broader than 
long, the inner side and outer end nearly rectilinear, the articulated edge 
rounded. Upper arm-plates very broad, and comparatively short, the 
breadth equal to about five times the length ; the outer edge with a slight 
notch or emargination ; many of the plates are irregularly broken into two 
or three pieces. Two arm-spines on the first plate, three on the second, 
four on the third, five on the fourth, seven on the fifth, eight on the sixth, 
nine on the seventh, ten on the eighth, and eleven on the succeeding ones 
as far as the middle of the arms. These spines are closely crowded, 
appressed, mostly oblong, with blunt points, about two-thirds as long as the 
breadth of the side arm-plates; the upper ones smaller and shorter; the 
lowest one larger and stouter than the rest. 
Colour of the disk uniform yellowish brown in the dry specimen. 
Arms—above—brownish yellow with an orange tinge, thickly covered with 
small round purplish-brown spots, some of which occur also on the upper 
arm-spines, and upper part of the side arm-plates. Lower surface, uniform 
dull yellow.
