REPORT ON Till-: AMPHIPODA. 1529 



uropods, but not nearly to the apex of the inner ramus, the length nearly twice the 

 breadth at the base, the apex not quite acute. 



Length, about half an inch, when fully extended. 



Localities. — March 15, 1874, south of Australia; lat. 39° 45' S., long. 140° 40' E. ; 

 surface ; surface temperature, 60 o- 2. Ten specimens. 



October 1875, South Pacific, surface. Five specimens. The specimen examined 

 was a male, and differed from the specimen above described in having the third 

 joint of the fifth perseopods distally narrowed, almost acute. 



Remarks. — The specific name is given in compliment to the distinguished zoologist, 

 to whose highly important work, Die Platysceliden, reference has been so frequently 

 made. The present species has many points of resemblance to Parapronoe crustulum, 

 Claus, from "the Atlantic Ocean, Lagos, Zanzibar"; it differs from that species in 

 the shape of the wrist of the first gnathopods, in the more irregular inner margin to the 

 wrist process of the second gnathopods, in the more produced third joint of the fourth 

 peraeopods, and in the widened rami of the second uropods. 



Parapronoe i clausoides, n. sp. (PI. CXCL). 



This species seems to unite some of the characters of Parapronoe clausi, just de- 

 scribed, with some of those of Parapronoe crustulum, to be described presently. The 

 head is large and rounded ; the first three pleon-segments have the postero-lateral angles 

 acutely produced, that of the first segment most strongly, the lower margin being 

 excavate in front of the tooth; the fourth segment is much shorter than the composite 

 following segment ; the body quite free from spots of colour, and in this respect differing 

 from both the species above mentioned. 



The Upper Antennas are those characteristic of the female ; the first joint of the 

 peduncle longer than broad, with sinuous margins, the second short, broader than long ; 

 the long first joint of the flagellum somewhat curved and tapering, carrying on the con- 

 rave margin nine pairs of filaments ; the second joint of the flagellum is much more 

 slender than the first and less than half as long ; the third much more slender than the 



aid, more than half as long. 



Lower Antennas. — The gland-cone prominent ; of the four free joints, which are 

 slender and not folded, the first is longer than the two following together, the third a very 

 little longer than the second, and the fourth than the third. 



The Mandibles are of the usual character, but in the female without palp. The figure 

 m.m. represents them drawn apart at the bases but with the distal ends and the outer- 

 most teeth of the cutting plates overlapping, close to the small almost semicircular upper 

 lip.
