arc (listiiictly paiicil. On the nK-iliaii line below tlie intestine the end.s of each 

 glanilular mass meet an<l join into one duet, the one 1 have just referred to. The free 

 ends of the <i;laiidular masses are attached by mesenteric tis.sue to the ventral or sul>- 

 intestiiial blood trunk. 



A much .smaller tubular gland of the same nature runs between the dorsal 

 vessel and the intestine; discharge duct unobserved. A yet smaller glan<l is seen 

 above the sid)ventral vessel in the same somite as the former; its discharge duct could 

 not be followed. 



These glands stain exactly as the eoiiunou >ti|ira-|i!i;iiyngeal glands and septal 

 glands, but they show no similarity as regards reagents with the chloragogic cells of 

 the intestine and blood vessels, in corres[)onding places in the .somites posterior to xi. 

 The septal glands appear to be of about equal size, a close examination being im- 

 possible, from want of sufficient material. 



Other glands are found in the epithelial walls of the intestine, arranged in 

 clusters, like the cloves in a garlic. They are scattered about at short intervals among 

 the epithelial cells, and appear of the same nature as those I have described in Ar- 

 gilophilus, but they are not as numerous as in that species. They do not stain freely, 

 but stand out bright and [)elliicid aniong llie daiker staining cells.

Gizzarch are connected by a very thin wall of the .same nature as the (esophagus. 

 As far as I can make out the gizzard must be in v and vi, at least the posterior gizzard 

 is bound liy the sc|itnm separating vi and vii. The ciii-iilar muscular layer is about 

 30 strands wide, and is at the widest place about four times thicker than the epithelial 

 layer and cuticle together. The whole width of the gizzard wall is little more than 

 twice that of the bo(l3-wall in that somite. The longituilinal muscular layer of the 

 gizzard is oidy one single stiand thick, and the thickness of this strand is less than 

 any one sli'and of the eircidar layer of the gizzard, The epithelial layer is com- 

 paratively thick, about one-lifth (jf the whole gizzartl. It contains the same peculiar 

 glands as I figured in Benhamia. 



Spermathecii;. The absence of diveiticula is interesting in as much as most 

 species of related genera possc-s ihcni. Tlieic are, Imwever. some warty eU-vatiuiis. 

 The niiiscidar oi- l)asal duct is very long, slender and tnladar, several times longer 

 than the up[)er ovoid sac (lig. 74). The muscular part offers no peculiarities of 

 structure. The spermathec;e occupy each only one somite. They stand upright fol- 

 lowing close to the anterior surface of the septum. 



Testes are greatly lohed and are situated high up nn the >(|itiini. just as are the 

 ovaries. 



S/tcrjndurfx iind ciliated rosettes. The spermducts are separated, but enclosed 

 ill a coininon muscular sheath until somite x.\i is reached. Ketween xx and xvi the 

 two ducts fuse into mic liinicii, wliicli upciis (uit iiild the center of somite xxi. The 

 double luiiicii runs along the circular iiiu>ciil;ir layer forward iiiilil somite xiii xii, 

 when the respective ducts rise u|>\var(ls following the septum to tlii' ovary and testes. 

 From here on forward each duct is thicker and inuscidar, anil instead of following the
