 from Trematomus bernacchii ; in some cases the rosiellum was not evaluated.

I'lii'itxil. . The two sexes are of almost similar size and shape : in some eases the 

 luirsi in the male is extruded from the centre of the posterior rounded end as a 

 shallow funnel. The liodv is cylindrical, of aliout I'D cm. to L '3 cm. in length and 0".\ cm. 

 in diameter. The liodv tapers anteriorly to form a narrow neck '1 mm. IOIIL; 

 (I'l. II. fin. 10, f), which terminates in an almost globular head. This spheroid head lias 

 an armature of spines set nimn coarse chitinous bases on its upper aspect (Fig. 1 ().//). The 

 -pine- are arranged in somewhat irregular series; there are five distinct rows on the 

 peripheral poii inn. lull those lining the sulciis surrounding the rostellum are verv 

 irregular. There are about ten rows in all. Their arrangement is somewhat irregular 

 and the exact determination of their number is difficult. The shape of the head and the 

 roughened appearance, due to the spines, remind one vividly of the rose ot a watering- 

 can. At the summit of the head there is a partiallv retracted rostellum (Fig. 10, n), the 

 unarmed base of which extends through the head to the insertion of the neck. The 

 hooks on the rostellum differ markedly from those on the head : thev are smaller and 

 more pointed. There are twenty longitudinal rows, each composed of three hooks. 



In the male the prostatie glands (Ki^. 10, c) are ^reatlv elongated and deeply 

 pigmented.
