| Abstract | ||
| This study was showed that different measurements of the shell and buccal mass (jaw and radula) of the gastropod genus Monacha sp.Which collected from five districts of Sharkia Governorate with different shell diameters included 10-10.9, 11-11.9, 12-12.9 , 13-13.9 and 14 -14.9 mm. The snails with shell diameters 10-10.9, 11-11.9 and 12-12.9 mm were glassy color in all districts, while snails with shell diameters 13-13.9 and 14-14.9 mm were chalky color. Jaw was found crescent shape , pale to dark brown in color , transversely ribbed , number of ribs differed from shell diameter to another with general mean values of 15, 13.6, 12.8, 13.6 and 14 ribbon for shells 10-10.9, 11-11.9, 12-12.9, 13 -13.9 and 14-14.9 mm, respectively. Number of teeth columns and number of teeth in each row in radula of different shell diameters 10-10.9, 11-11.9, 12-12.9 , 13-13.9 and 14 -14.9 mm were ranged between values (Fakous) (51:57) column, (105 : 137) teeth)), (Hehia) ((49 : 63), (101 : 135)) , ,(Belbies) ((50: 57), (107 : 128)), (Meniet-Elkamh) ((54 : 63), (112 : 148)) and (Kafr –Sakr) ((56 : 61), (115 : 146). , respectively in different localities. The total number of teeth calculated to formula in general mean of different shell diameter examined of Monach sp were 13724.48 teeth, 13660.32, 13043.80, 15929.4 and 15408.12 for shell diameter, 10-10.9, 11-11.9, 12-12.9, 13-13.9 and 14 -14.9 mm, respectively. Also rapprochement between number of teeth in both shell diameter of 10-10.9 & 11-11.9 mm and 13-13.9 & 14-14.9 mm. | ||
