1256 THE VOYAGE OF H.M.S. CHALLENGER. 



the surface near the apical margin and the distal part of the inner margin there are 

 fourteen slender spines of greater length than those on the apex. 



Second Maxillse. — Inner plate shorter and more oval than the outer, with many 

 slender spines round the apical margin and descending the inner margin for some 

 distance ; the outer plate oblong, with many long spines on the apical margin, of gradually 

 greater length as they approach the outer corner, where there is one short spine ; the 

 apical margin for the most part truncate, but with an oblique portion where it joins the 

 inner margin. 



Maxillvpeds. — The inner plates small, scarcely reaching beyond the base of the first 

 joint of the palp, widening distally, with two long slightly feathered spines near the 

 distal part of the inner margin, and seven on or near the broad slightly denticulate 

 distal margin, which also carries two or perhaps three distant spine-teeth ; the angle 

 where the distal and inner margins meet is finely but irregularly pectinate ; the outer 

 plates small, reaching little beyond the first joint of the palp, with eight rather long 

 spine-teeth on the straight but denticulate inner margin, and on the oblique denticulate 

 apical margin a spine-tooth at the inner corner, and a long curved spine at the outer ; 

 the first joint of the palp short and stout, with spines on the inner margin, and one 

 below the centre of the outer ; the second joint stouter than the first, scarcely twice as 

 long as broad, the inner margin fringed with long spines, of which there are two near 

 the outer apex ; the third joint intermediate in length between the second and first, its 

 distal half crowded with spines, especially on the inner surface ; the finger abruptly 

 narrower, not very much shorter, than the third joint, with a short dorsal cilium near 

 the hinge, its surface covered with rows of minutely pectinate scales or appearances that 

 may be so described ; there is a setule on the inner margin at the base of the slightly 

 narrowed furred tip. 



The limbs are in close agreement with the figures and descriptions given by Mayer 

 for this species. 



Length. — Some of the male specimens were about an inch long from the rostrum to 

 the pleon, with the gnathopods inserted behind the centre of the body ; in these specimens 

 the upper antennas were more than half an inch long, the total outstretched length 

 including the antennas and hinder perseopods not being less than an inch and three- 

 quarters. 



Locality. — "Screw of ship, off Cape of Good Hope, 18 Dec. 1873" (corresponding 

 with Station 142 ; lat. 35° 4' S., long. 18° 37' E.). Several specimens of both sexes and 

 i if various sizes. 



Samboangan, Philippines, February IS, 1875 ; lat. 2° 56' N., long. 134° 11' E. One 

 i | 'crimen, male ; total length about seven-tenths of an inch.
