NO. 2174. EARTHWORMS OF THE FAMILY LUMBRICIDAE— SMITH. 171 



Tlie clitelliini is sharply defined at its anterior and posterior limits 

 on 22 and 29, as described, but it has an uneven development and 

 extends slightly ventrad of two rather thick patches on 27 and 28, 

 which I assume to be the tubercula pubertatis which Eisen described 

 and figured. They seem too far dorsad and too similar to the clitellar 

 mass about them to be homologous with the tubercula pubertatis of 

 typical Lumbricidae. They are dorsad of seta line h. The first 

 dorsal pore is on 5/6. The spermiducal pores are on 15; dorsad of h, 

 about I he. The oviducal pores are on 14, slightly dorsad of h. 



Tlie septa 6/7-9/10 are slightly thickened, 8/9 being somewhat 

 thickest, and 13/14 and 14/15 are also shghtly thickened and about 

 equal to 8/9. The longitudmal partitions of the calciferous gland are 

 apparently about 40 in number. The exact number can not be ascer- 

 tained from longitudinal sections of one side. The last pair of hearts 

 is in 11. Spermaries and spermiducal funnels are in 10 and 11 and 

 present no peculiarities. Tlie sperm sacs are in 11 and 12 and have 

 the ordinary appearance and relations. Spermathecae are lacking. 



In his general comment on this species, Eisen refers to the peculiar 

 position of the setae which gives a rectangular appearance like that 

 of H. tetraedrus, and states that it is very characteristic of this species. 

 The specimen bears out his statement and also his figure, except as 

 to the setal distances a6 and dd mentioned above. 



H. tumidus was found under moss and leaves in damp woods at 

 Mount Lebanon, New York (New England of Eisen's paper). No 

 other locality has been reported unless it should develop, that the 

 species is identical with H. gieseleri hempeli Smith, described below.

Length, average 5.5 cm. Somites, about 110. Color of antero- 

 dorsal part, faint red with bluish iridescence. Prostomium, epi- 

 lobic ^ Setae, closely paired; slightly posterior to the clitellum, aa : 

 &c : (^(^=10 :9 :26. CHtellum on 20-^ 30; saddle form, extend- 

 ing ventrally nearly to h. Tubercula pubertatis, lacking. First 

 dorsal pore on 5/6. Spermiducal pores on 15; a little dorsad of 6. 

 Oviducal pores on 14; slightly dorsad of h. Septa 6/7-14/15, 

 slightly thickened. ''Hearts" in 7-11. Sperm sacs in 11 and 12. 

 Spermathecae lacking. 



The description is taken from Ude's paper which was based on a 

 collection from Georgia. Specimens in the possession of the writer, 

 which he assumes to belong to this species and which were collected 

 in Florida by Mr. A. Hempel, agree very closely in most respects 

 with Ude's description. The length is greater, 6-10 cm., but the
