CAI.IFOKNIA KUDKILID.E. 35 



Septal Gl/iiuh (Hgs. 2(5, 27, '2U). When the worm is laid opon and the cavity 

 viewed t'roin above, it is seen that there are 4 pair of septal glands siirroiiii(Hii<;- tlie 

 oesophaf;iis in somites v, vi, vii and viii. In liiis view the anterior i;iand appears the 

 hirgest, and tiie posterior one in viii the smaUest. 'I'his is, iiowevcr, only nn ilhisionary 

 a|)pearanee, caused l)y the position of the glands. There is in reaHty not any very 

 consich'rahh' difi'erenee in their size, as may he seen wlien separated and spread out. 

 Seen in a slightly eccentric longitudinal section, the gland in vi appears the largest lioth 

 ahove and hcdow the (jesophagus, though in sonu; sections the lower part is not as large 

 as the lower part of the gland in vii. The anterior gland in v is short hnt hioad. The 

 one in vii is larger than those in v and viii, hut smaller than the one in vi. The 

 upper part of the gland in viii is larger than the corresponding part of v, the lower 

 part of the latter heing the smallest. As will i)e seen, all the glands -.[w develdped, 

 both superiorly and inferiorly, as regards the (esophagus, but the glands on either side 

 in the somite do not connect, but only touch. There is a slight, but irregular lobing 

 of the glands, frcHjuently unequal on either side, as one gland may be almost entire, 

 while the other again is furnished with three indentations. On the under side of 

 each main gland there is a smaller lobe, almost entirely separated from the rest (fig. 

 29). The glands are furnished with blood from the subresophageal longitudinal blood- 

 vessel wliich jirojects a branch to each gland, on which it again divides in two or 

 three parts (Hg. 2i)). I may add that the septal glands are very large, almost lilling 

 the re.spective somites, and as compared with those of Ddtania elegans, about three 

 times as large, considering however the relative size of the two species. The glands 

 are nearly similar to those of TJe.Itunia Beiiha/iii, but with more unequality as to size. 



Salivnvij or Pharynyeal Glands (fig. 26). These glands resemble those of the 

 preceding species, Delfanln ekf/nns, in general appearance. There are two very long 

 glands behind the brain, attached on the underside of the two long muscular bands 

 which stretch upward. The anterior one of these is the smallest and rather short, the 

 second in order from the brain is the longest. The posterior gland, which forms the 

 posterior projection of the pharynx, is much shorter, more compact and roundetl 

 than the corresponding gland in Deltnnin degan)i. The whole mass of glands projects 

 much less posteriorly than the glandular mass of the pharynx in that species. 



SjKrmafheca (figs. 30, 31, 32 and 30). These organs are prominent and char- 

 acteristic of the species. There is one pair in somite ix opening in the inter- 

 segmental groove between that somite and viii. The external pore is in front of the 

 inner couple of setfe, but not interior to the setse. The organs are thick, opaque and 

 of the form of pointed sacs, each one with two diverticula, one on each side, which 

 connect with the main sac close to the external pore. The outline of the sac is irreg- 

 ular in some places, toward the inner apex assuming the appearance of one or more 

 warty diverticula, which, however, never assume the size of the diverticula. Of tliese 

 latter there are one pair which are slender, cylindrical, of more or less irregular out- 

 line with the apex sometimes slightly wider, sometimes heli.K-like, turned on itself. 

 The lower part of the spermatheca is muscular, but this muscular part is quite small,
