ject during the year, and find the evidence very conflicting. My 

 notes suggest that the salivary glands and spermatheca3 vary with 

 tiie age of the worm, and may l.)e larger in the young than in the 

 adult.

21. Fridericia glandidosa Southern. 



First described in 1907 (Irish Naturalist, xvi. p. 7G, and fig.) 

 " from a single mature worm found on Lambay in 1906. Since 

 then I have found it (says Southern, Contributions, p. 162) in 

 large numbers in several other localities in Ireland, and have also 

 received it from Scotland. This material enables me to cjive a 

 more accurate description of the species." Length 15-25 mm. ; 

 setaj 6-8 in front. Salivary glands consisting of a short basal 

 portion and slender branches. The spermathecie have a character- 

 istic shape, and there are occasionally glands at the base. When 

 I found it this year it seemed so familiar that some of my earlier 

 records probably refer to it. 



British Records. — Lambay, Dublin, and elsewhere in Ireland ; 

 Edinburgh, December, 1907 (Evans) ; Acresford, near Ashby-de-la- 

 Zouch, October 3, 1911, first positive English record. Five 

 specimens, all adult. We need fuller information as to the period 

 when maturity is attained by the different species. 



22. Fridericia callosa Eisen. 



I place here for the present, an interesting worm found by me 

 on October 3, 1911. It does not fully agree with Eisen's descrip- 

 tion, and in some respects recalls certain species described more 

 recently by Issel. j\Iy notes are as follows : A sluggish worm, 

 perfectly adult, 8 mm. in length, with 40 segments. Appears 

 yellowish brown to the naked eye, except where the eggs are. 

 Setffi 4 in front, unequal in length ; 2 behind equal. The brain 

 is convex before and behind, about three times as long as broad, 

 and is remarkable for the dark greeir cells in the convexities 

 (fig. 5). Three pairs of septals of unusual shape and structure, 

 front pau' very massive, the whole set more complex than is the 

 rule. Usually two rings of vacuolar cells in the epiderm of each 

 segment, one in line with the sette and one behind. Girdle 

 with large irregular polygonal glands of about 30 rows, covering 

 xii-^ xiii. Chloragogen cells large, irregular, dark. Nerve-chord 

 enlarged in the front segments. Salivaries present, tips apparently 

 forked. The spermathecie have a fairly large duct, without glands 

 at the exterior. Tlie ampulla is somewhat large, and sessile 

 glands or diverticula, small — 4 or more in number — lie between 

 it and the duct (fig. 6). In the front segments (7 and 8) tha
