scni, and some otliers, all of which will be duly recorded when my 

 report is drawn up. I venture here to describe one as new. 



28. Fridericia microcara sp. n. 



A large stout worm about an inch to an inch and a half, or 

 25 to 30 mm. in length, whitish opaque with somewhat yellow in- 

 testine, and 60 to 70 segments. Setfe 3-6 in front, inner pair very 

 small indeed ; 0-2 behind, being sometimes totally absent. Six or 

 eight rows of irregular strire or vacuoles in each segment ; head 

 with very large, irregularly lunate glands. Whole worm larger

and more opaque than striata, and distinct from ratzeli, which was 

 found in the same locality. In some respects near heyemon and 

 ■mayna, but having colourless blood. Opaque under the Microscope 

 and very difficult to diagnose while living. 1 was particularly 

 struck by the small size of the brain in comparison with the body ; 

 convex behind, with strong attachments. Salivary glands present, 

 small, branched, posterior extremity reaching only to the front of 

 the first pair of septal glands (fig. 11). Dorsal vessel rising in 

 18, with strong double commissures in segment iv. Anteseptal

of nophridia large, brown in front segments, nearly half as long as 

 post-septal. Duct stout, about as long as post-septal, from the 

 middle or anterior third of wdiich it springs (fig. 12). Funnel 

 of sperm-duct about four times as long as broad, without a collar. 

 The most remarkable feature, however, is the spermatheca. The 

 duct is somewhat stout, and has one or more large glands at the 

 opening between segments 4/5. The many diverticula cluster 

 around the intestine and ampulla, and almost fill the coelom with 

 their brown masses. A beautiful microscopic mount which I was 

 able to prepare \vas unfortunately spoiled in transit to my home. 

 It is, however, still adequate, along with my drawings of the Hying 

 animal, for the preparation of an iihistration (fig. 13).
