rest of the axial canal of the collar-cord being broken up 

 into the smaller spaces of the cord). They are certainly not 

 like the anterior dermal pit which is present in the new 

 species described here, aiid which has a proper epidermal 

 wall. The arrangement of the intestinal pores is quite 

 different in my largest specimen (the only one which 

 possessed the post-branchial region) from that given by 

 Spengel. Spengel mentions nine unpaired intestinal pores, 

 the first being placed on the right side and the rest on the 

 left, and, some distance behind these, three pairs of paired 

 intestinal pores. In my series of transverse sections I 

 counted about sixty of the former and six pairs of the latter. 

 The arrangement of the unpaired pores is very irregular. 

 They lie now on the left side, now on the right ; some of 

 them are paired, but the majority are unpaired. The gonads 

 begin a little behind the anterior end of the branchial region, 

 and extend into the commencement of the liver region. 

 Marion's statement that they are confined to the branchial 

 region is thus certainly not true of the males. The testes 

 are paired, iri-egularly lobed, and transversely elongated 

 bodies. These dorsally placed masses bend at the sides of the 

 body, and extend into its ventral portion. They open by ducts 

 along the submedian grooves. 



Dolichoglossus bournei. — Two specimens of a new 

 species of Dolichoglossus were obtained. The proboscis, collar, 

 and a portion of the branchial region were alone present. 



The animal is small. What at once enables one to assign 

 it to its proper place is the great length of the proboscis. 

 When moderately extended, it measured about 9 mm. in 

 length, and after preservation about 6 mm. It is depressed, 

 and its base is twice or three times as broad as the tip, its 

 greatest breadth at the base being nearly 2 mm. The deep 

 longitudinal groove present on the dorsal surface in the 

 species sulcatus and otagoeusis is absent. But in pre- 

 served specimens there is a shallow longitudinal depression 

 on the dor.sal side, extending forwards some distance from 

 the base of the proboscis ; there is a similar but less marked
