Scplid (-!lai((h (li<;s. l^C, 27, 29). When the worm is laid open and tiie cavity 

 viewed from above, it is seen that there are 4 pair of septal glands surrounding tlie 

 (Bsophaons in somites v, vi, vii and viii. In this view the anterior gland appears the 

 largest, and the posterior one in viii the smallest. This is, however, only an illusionary 

 appearanee, caused l)y the position of the glands. There is in reality not any very 

 considcrahlc difi'erence in their size, as may be seen when separated and spread out. 

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

 above and below the oesophagus, 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 l)ut broad. The 

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

 npper part of the gland in viii i-< larger than the corresponding part of v, the lower 

 part of the latter being the smallest. As will be seen, all the glands are developed, 

 both superiorly and interiorly, as regards the <eso[)hagus, 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, frequently uneqnal 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 l)l(iod- 

 vesscl which projects a branch to each gland, on which it again divides in two or 

 three parts (fig. 29). I may add that the septal glands are very large, almost filling 

 the respective somites, and as com|)ared with those of Ddtjiida elef/diis, about three 

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

 are nearly similar to those of Deltania Benhnmi, but with more uneipiality as to size. 



Saliciin/ or I'linnjiujeaJ. (/Idtuh (fig. 2(5). These glands resemble those of the 

 preceding species, IMtanin ekgnns, in general appearance. There are two very long 

 glands behind the i)rain, attache(l on the underside of the two long nniseular bands 

 whicli 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, moi'e compact and rounded 

 than the corresponding gland in Deltania ekgans. The whole mass of glands projects 

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



8j>ermatheca (figs. 30, 31, 32 and 39). 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 conple of setiie, but not interior to the seta?. 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 th<i inner apex assuming the appearance of one or more 

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

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

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

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