what longer than the end joint. The first joint lias no bristles. The second joint has at the 

 middle a single bristle, which is somewhat longer than this bianch; this bristle has some rather 

 long hairs proximally of the middle, but aj^art from these it is almost or quite bare. Distally 

 on this joint there are five natatory bristles, which are of about the same length and type as the 

 long natatory bristles on the exopodite. The end joint has four bristles distally. three of which 

 are of about the same length and type as those on the preceding joint, the fourth somewhat 

 shorter. All the joints are bare. 



M a n d i b 1 e (see the appended fig. 5): — This is of about the same type as m Polycnpe 

 frequens G. W. MCi>I.Ei{; see this author. 1X94. pi. 7. fig. 7. Protopodite: This has 

 three rather distinct joints. The procoxale has no bristle oi' eiidite. The coxale is developed 

 ventrally as a long, powerful endite which is furnished distally with three powerful pointed teeth, 

 with a smaller tooth of the same kind between the two anterior ones, and two short-haired 

 bristles, one of which is about as long as the large teeth, the other exceedingly short. .4t the 

 middle of the posterior side of this endite there is, in addition, a rather short bristle with short 

 hairs. Basale: This is somewhat swollen ventrally and is there furnished with f'oiu- subequal 

 bristles, which are plumous at the middle and have short hairs distally; these bristles are about 

 as long as the height of this joint. Somewhat in front of and dorsally of the middle this joint 

 has on one side a rather short plumous bristle as well. Exopodite: There are indications 

 of a division into two joints. The proximal joint has a single bare bristle dorso-distally, which 

 is about as long as this joint. The distal joint is narrow and cylindrical and has no bristles. 

 E n d o p o d i t e: This has two joints. The first joint has ventrally at and somewhat prox- 

 imally of the middle three subequal bristles of about the same type as the ventral bristles 

 on the basale and about as long as or rather slightly longer than these. Dorso-distally on this 

 joint there are two subequal bristles of about the same length as the whole of this limb; these 

 bristles are furnished proximally with rather long hairs (these hairs are numerous, especially 

 on the anterior side of the anterior one of these two bristles) and have short hairs distally. The 

 end joint is extremely small and is furnished with two subequal bristles of about the same type 

 and length as the ventral bristles on the first endopodite joint. Pilosity: On the posterior side 

 and distally on the endite of the coxale there are short, stiff hairs, situated rather close together. 

 Dorsally on the distal joint of the exopodite there is a collection of rather long, fine hairs. The 

 first endopodite joint is also furnished with hairs, some on the side and some ventrally-proximally. 



Maxilla (see the appended fig. 6): — This is of al)out the same type as in Polycope 

 frequens 0. W. MleeeU; see this writer, 1894. pi. 7, fig. 14. Protopodite: This is 

 distinctlv three-jointed; all the joints are strong and of about the same length. Procoxale: 

 Ventrally-medially-distally this has a rather weak endite, armed with five bristles of somewhat 

 different lengths, the longest one being somewhat shorter than the height of this joint, the 

 shortest about a third of this length; they are all furnished with fine and rather long secondary 

 bristles, situated close together. Ventero-distally on this joint there are also three bristles of 

 about the same type and length as the longest ones on tlu> above-mentioned endite. Apart 

 from these this joint has no bristles. Coxale: This has two veiy weak endites ventero-medially. 

 Oil the i)ro.\iinal eiiditc there are four long-liaiivd bristles; the two ])i'oximal (mes of these bristles
