350 ASYOHIS BICEPS. 



This is a large form measuring in its incomplete condition 110 mm. and probably 

 exceeding 5 in. in length, and having a diameter of 3 or 4 mm. The anterior region is, 

 however, absent or represented only by a small papilla projecting forward from the cica- 

 trising end of the trunk. Judging from the appearance of the specimen and the condition 

 in other forms only a bristled segment with the head and peristomial segment are absent, 

 this making the total number of bristled segments nineteen. 



The anterior region has somewhat the same arrangement of the glandular tissue as in 

 Maldane Sarsi, though of course it is only present in the specimen from the second bristle- 

 tuft. The second and third bristled segments have a glandular ventral surface which is 

 continuous with a nearly complete dorsal investment, Dorsally, however, a blank occurs 

 from the anterior border of the fourth segment, which has a thin glandular streak, 

 backward. A thick streak occurs dorsally opposite the bristles of the fourth segment, 

 but the great glandular belt from the ventral surface appears at each side dorsally in the 

 second ring of the segment at the bristle-tuft. The first ring of this segment ventrally 

 is less thickly glandular than the second, which has a lozenge-shaped area with fewer 

 glands in the mid-ventral line. The great fifth segment shows dorsally the thick, bifid 

 lateral pads on each side of the bristles, whilst ventrally it has a semicircular patch in front, 

 the thin ends being visible dorsally, and a broad and continuous belt behind. The sixth has 

 a glandular streak dorsally between the bristle-tufts of opposite sides, and the ends of the 

 ventral belts are seen in front and at the feet, as in the previous segment. Ventrally the 

 anterior only exhibits a fissure, wider laterally, between it and the continuous and broad 

 posterior belt of glandular tissue. The next (seventh) segment has anteriorly the dorsal 

 ends of the glandular area of each foot, as well as a small portion of the anterior ventral 

 belt seen at the sides. Ventrally a somewhat semicircular glandular area lies in front, 

 its posterior edge in the preparation being somewhat indefinite. The glandular belt at 

 the feet is also continued from side to side. Thereafter, as a rule, the bifid glandular areas 

 at the feet are alone visible from the dorsum. Ventrally the belt between the feet is 

 distinct at the eighth, ninth, and tenth, is more or less interrupted on the eleventh, twelfth, 

 thirteenth, and at the succeeding feet the glandular tissue is confined to the sides of the 

 feet, forming prominent ovoid enlargements in each case. A median streak occurs in the 

 mid-ventral line from end to end. The proboscis is a flattened bladder-like organ with 

 papillae. 



In the general form of the body this species approaches that of Maldane Sarsi, though 

 in the large example the last four bristled segments were more prominent and closer 

 together. They are followed by a narrow ring and then the anal plate. The first six 

 bristled segments are comparatively short, whilst those following are longer, and the 

 fourteenth and fifteenth are again somewhat shorter. The last four diminish progres- 

 sively, and in the prominent and broad glandular feet agree with the figure of Maldane 

 biceps given by Malmgren. A single narrow ring devoid of bristles follows the nineteenth 

 bristled segment, and it has a glandular area at each side. The anal segment (Plate 01, 

 fig. 7 a) has dorsally the transversely ridged eminence for the vent, with its valve-like 

 plug at the opening behind, a process passing off from this toward the median fissure of 

 the anal cup. This cup is broader dorsally than ventrally, with an acute fissure in the 

 mid-dorsal line and a more obtuse one in the mid-ventral line, the lateral slit at each side
