canals, two of which are not separated until so far outside the periphery of the stomach that their 

 gonads are confluent (Plate IV, fig. 5); the canals are very irregularly arranged. 



Loc. 2. -- (textfig. 9^): Diam. 24 mm, <j>, 17 radial canals, one of which (x) is quite young and 

 terminates blindly; arrangement irregular. 



Loc. 3. Specimen No. I (textfig. gd; Plate IV, figs, i and 3): Diam. 35 mm, <? } mature, 15 

 radial canals, regularly arranged in 4 groups of 3-4-4-4 canals. Specimen No. II (textfig. gc): Diam. 

 45mm, ?, gonads containing eggs of different sizes; 13 radial canals in groups of 3-3-3-4; 442 tentacles 

 (with regard to the distribution of the tentacles in relation to the radial canals, see below). 



Loc. 4 (Plate IV, fig. 2): Diam. 35mm, $, 15 radial canals, fairly regularly arranged in groups 



of 3-3-4-5- 



Loc. 5. Specimen No. I (textfig. gf) : Diam. 25 mm, c?, 14 radial canals, irregularly arranged, 

 one of the canals (x) is quite young and terminates blindly. - - Specimen No. II : Diam. 26 mm, c?, 17 

 radial canals, 5-4-4-4, in the third group one small blind canal. Specimen No. Ill (textfig. gg): Diam. 



33 mm, <$; the specimen has 2 stomachs; 6 canals issue from the one of the stomachs, 8 from the 

 other. The distance between the stomachs is 2 mm. The dimensions of the stomachs are, respectively, 

 3.8 by 3.0 mm and 4.0 by 2.7 mm. 



Loc. 6. Specimen No. I: Diam. 28 mm, $,15 radial canals, 3-5-3-4. -- Specimen No. II: Diam. 

 32 mm. Specimen No. Ill: Diam. 36 mm, c?, 15 radial canals. Specimen No. IV: Diam. 37 mm. - 

 Specimen No. V : Diam. 40 mm. 



Loc. 7. -- Specimen No. I (textfig. 9^): Diam. 23mm, <?, 15 radial canals, one of which ends 

 blindly (x), but has already a short gonad. Specimen No. II (textfig. 92): Diam. 28 mm, J*, 14 radial 

 canals, 4-4-3-3. -- Specimen No. Ill (textfig. 9 k) : Diam. 40 mm, <j>, 17 radial canals, 3-4-5-5. Two of the 

 canals, issuing from the periphery of the stomach, make an anastomosis, from which 3 canals issue. 

 In the 2nd group there is a young canal (x) beginning to develop. 



Loc. 8. Specimen No. I (textfig. 9 /) : Diam. 30 mm, ., 16 radial canals, irregularly arranged. 

 - Specimen No. II: Diam. 35 mm, c?, 15 radial canals, 3-4-3-5. -- Specimen No. Ill: Diam. 35 mm, <?, 

 17 radial canals. 



Loc. 9. -- Specimen No. I: Diam. 30 mm, $, 15 radial canals. Specimen No. II (textfig. gm): 

 Diam. 30 mm, cT, 15 radial canals, irregularly arranged. -- Specimen No. Ill (textfig. gn): Diam. 44mm, 

 J 1 , sexual products spawned, 16 radial canals, irregularly arranged. 428 tentacles and 80 marginal 

 vesicles (see below). Specimen No. IV (textfig. 9 o): Diam. 56 mm, .; the individual has spawned, 

 but the gonads still contain some eggs. 14 radial canals, 3-3-4-4. 83 marginal vesicles (see below); the 

 tentacles cannot be counted. 



Loc. 10. -- Specimen No. I: Diam. 33 mm, <?, 15 radial canals, 3-3-4-5. Specimen No. II: Diam. 



34 mm, cT> 15 radial canals. 



Loc. ii. -- Diam. 45mm, $, fully mature, 15 radial canals. 



Loc. 12. -- Diam. 40 mm, <?, 12 radial canals, 3-3-3-3. 



Loc. 13 (textfig. gp): Diam. 35 mm, ?, 13 radial canals, 3-3-3-4. 



Loc. 14 (textfig. 9 q) : Diam. 30 mm, <?, 13 radial canals, 3-3-3-4. 



Loc. 15 (textfig.gr): Diam. 20 mm, $. The radial canals are abnormally arranged. 12 canals
