F.R. WANLESS AND R. HUNTER 



Fig. 26 Criconema demani (Micoletzky, 1915). A, B, D, female 1. A. 

 anterior region; B, posterior region; D, tail. C, E, female 2. C, posterior 

 region; E, tail. Scale bars a = 30 \xm, b = 10 |jm. 



Discocriconemella sp. 



(Fig. 27) 



Material examined. Fort Augustus Bay: 92 m; core 4, 1 9 



Female. (n = 1). L = 257|im;a = 6.2;b = 3.1;c= 18.2; V = 89; 

 R - 98 (ventral side); Rex = 38; RV = 1 3; Ran = 8; VL/VB = 1.0; tail 

 = 14.1 um. 



Labial annule discoid, offset from body. Body annules retrorse 

 except fifth to twelfth which are anteriorly directed on ventral side; 

 annules with anastomoses and finely crenate posterior edges; out- 

 line somewhat angular. Spear 54 um long, knobs 7.4 um wide with 

 anterior surfaces indented. Oesophagus about 82 um long. Vulva 

 apparently closed. Anterior genital branch poorly preserved. 

 Spermatheca filled with sperms. Tail terminus bluntly rounded. 



Remarks. This female closely agrees with the description of D. 

 limitanea Luc, 1959 by Rashid et al., (1987) but differs by having 

 fewer anteriorly directed annules (5th to 12th in this female vs 4th to 

 23rd annules in their population). Possibly this is the first record of 

 this tropical genus in Europe. 



Hemicycliophora sp. 



Material examined. Foyers Plateau: 159 m; core 14, 1 9. 



REMARKS. Specimen in very poor condition and not worth des- 

 cribing. 



Ogma sp. 



Material examined. Fort Augustus Bay: 92 m; core 3,19. River 

 Oich:0.31 m; core 31, 19 



Fig. 27 Discocriconemella sp. A-C, female. A, habitus: B. posterior 

 region; C. anterior region. Scale bars a = 30 |im, b = 20 \an. 



Remarks. Neither specimen is in good condition, the spear knobs 

 are missing; the oesophagus and genital structures are poorly pre- 

 served. 



Paratylenchus sp. 



(Fig. 28) 



Material examined. Fort Augustus Bay: 92 m; core 4, 1 9. 



Female, (n = 1 ). L = 3 1 8 jam; a = 23.7; b = 4.6: c = 9.3; c' = 4. 1 ; 

 V = 77; tail = 34.2 um. 



Fig. 28 Paratylenchus sp. A-D, female. A, oesophageal region; B. 

 habitus; C, lateral field; D, tail. Scale bars a = 10 |im. b = 50 \xm.
