Figure 6.— Schematic representation of a functionally female ovary from Centropristis striata. A) 

 Ventral view of ovary showing the alamellar region. Cross sections of the ovary were made in planes 

 I-I and II-II, and show the positioning of the primordial testicular tissue at the boundary of the alamellar 

 regions. B) An enlargement of the area indicated, showing the cellular relationships of the alamellar 

 area, testicular primordia and ovarian lamellae. AL = alamellar region, = oocytes, OL = ovarian 

 lamellae, OT = ovarian tunic, SP = chords of spermatogonia, TP = testicular primordia. 



Figure 7.— Photomicrographs of histological sections of gonads 

 from Centropristis striata. A) Cross section taken from the 

 posterior region of a functional ovary showing the alamellar region 

 and testicular primordia, 250 x magnification. B) Cross section 

 taken from the posterior region of a gonad undergoing transition, 

 250 x magnification. C) Cross section of immature testicular tissue 

 from a 133 mm SL fish, 100 x magnification. D) Cross section of 

 a simultaneous gonad showing active testicular and ovarian 

 development, 100 x magnification. AL = alamellar region, DO = 

 developing oocyte, OL = ovarian lamellae, OT = ovarian tunic, 

 S = spermatozoa, SP = spermatogonia, T = testicular tissue.
