148 Parharpinia, Amphilochidae 



Hoodlong, roaching almost end of peduncle of antenna 1. Side-plates 1 — 4, 

 hinder half of lower margin well fringed with setae, 4*^ as broad as deep, 

 excavation shallow. Pleon segraent 3. postero-lateral coruers subquadrate. 

 Eyes ovate, conspicuous. Autemia 1, 1^* joiut as long as 2*^ and 3"^ combiued, 

 2^ with fascicle of setae, flagellum subequal to peduucle or a little longer, 

 13-jointed, accessory flagellum not mach shorter, 10-jointed. Antenna 2, pen- 

 ultimate Joint of peduncle uot grcatly louger than ultiraate, with long setae, 

 flagellum rather longer than peduncle. 17-jointed. The long straight 3*^ Joint of 

 the mandibular palp is obliquely truncate at the apex. Palp of maxilla 1 com- 

 paratively large. Outer plates of raaxillipeds reach more than half-way along 

 the long 2*^ Joint of the palp and are fringed with a dozen gi-aduated spines serrate 

 on both cdges. As in Pontharpinia pinguis (p. 146) the 3^ Joint of the palp is 

 produced a little beyond the Insertion of the tinger, which is nearly as long as the 

 3*^ Joint, not tipped with a spine. Gnathopod 1, 5*^ Joint rauch shorter than 

 the oblong oval 6*^; palm very oblique, defined by a tooth with palmar 

 spines. Gnathopod 2, ö^^ Joint about as long as 6*^, which is similar to that 

 of gnathopod 1, not broader (rather broader, Haswell). Peraeopods 1 and 2, 

 the h^^ Joint lias the apical spine nearly as long as the 6^^ Joint, finger 

 rather short. Peraeopod 3, 2^ Joint not greatly expanded, more so above 

 than below, 4^^ to 6*^' with spines and long setae. 4^*^ rather shorter but 

 distally wider than 5**», 5*^ wider, scarcely longer. than 6*^. Peraeopod 4, 

 2^ Joint strougly curved and setose in front, bind margin nearly straight. 

 Peraeopod 5, 2*^ Joint as broad as long, not produced to end of 4**^, Branchial 

 vesicles on gnathopod 2 and peraeopods 1 — 5 large. üropod 1, peduncle 

 little longer than the equal rami. of which one has 4 lateral spines, the 

 other only 1. üropod 2, peduncle fringed with 10 outstanding spines, rami 

 a little unequal. üropod 3, rami longer than peduncle. not narrow, inner 

 smooth, only a little shorter than the 2-jointed outer, which carries spines 

 and setae. Telson as in Pontharpinia pinguis, the apices rounded. with setae 

 at exti-emity of outer margin. Colour yellowish (Thomson). L. about 9 — 14 mm.

Body rather short and stout. pleon narrow and sti'ongly flexed. Of 

 the side-plates some and always the 4*^ rather or very large (Fig. 40). 

 Antennae 1 and 2 rather short, seldom differing much in length, accessory 

 flagellum of antenna 1 wanting or small, Upper lip apically iucised. Lower 

 lip, inner lobes wanting or rudimentary. Mandible normal, except as to 

 molar, which varies from feeble or obsolete to strong. Maxilla 1, inner 

 plate small, palp 1- or 2-jointed. Maxilla 2 normal or degraded. Maxillipeds, 

 outer plates not very large, palp long, Guathopods 1 and 2 not very powerful. 

 Peraeopods 1 — 5 slender. Branchial vesicles usuaUy simple. Marsupial 

 plates often large with long setae, üropods 1 — 3, rami slender, Telson 

 entire, unarmed, (Fig, 39 p, 154).
