Biifo quercicus 121 



6. Several notes on males Or possible males might be in place: 



(a) 15.5 mm. specimen has i transverse fold from mouth angle to other 

 mouth angle. Is it to be a male? At this size these small oak toads 

 are little beauties: stripe down back very prominent from mouth 

 margin over snout to vent. Tubercles carmine tipped and at times 

 making a margin along light vertebral line. 



(6) 16 mm. has 3 transverse edges across lower throat. Is it going to be 

 a cf ? cf not functional at this size. 



(c) Of 4 specimens 14, 15, 16, 17 mm. we remark: two small ones darker 

 in color and will probably develop into cf s. No signs now. The 

 larger two are lighter, may develop into cf s. 



(d) One 18 mm. specimen black throat, two transverse folds, one of them 

 connecting angles of mouth; probably going to be cf . 



(e) One 19 mm. cf , throat in general not black, the evertible sac not 

 extening over pectoral region as lapette or apron. It is outlined in 

 front by two transverse ridges and behind in pectoral region by two 

 transverse ridges. 



(/) One 19 mm.c?', throat region with 5 or 6 transverse folds but no apron. 



(g) One 19 mm. cf , lower throat with good apron on breast. 



{h) One 19.5 mm. cf , dark throat and narrow dark triangle down middle 



of pectoral region. 

 (i) One 20 mm. cf, throat not very dark but has throat lapette. 

 (j) One 20.5 mm. cf , quite a throat apron. Do you suppose some queer 



oak toad noises are young males calling? 

 (k) One 22 mm. Lapette extends forward beyond chin. 

 (l) One 24 mm. Dark throat apron. No black excrescences revealed on 



thumb and second finger in alcoholics, 

 (m) One 24.5 mm. Possibly first and second fingers in life may seem to 



be a little more horny but it is not very well revealed in preserved 



material, 

 (n) One 26 mm. Apron on lower throat but throat light not dark while 



its mate, a female, has dark throat and heavily spotted breast. 

 (0) One 28 mm. Dark throat. Lapette covering 3 or more folds under- 

 neath. One or two ridges on front of pectoral region hid by apron. 



No excrescences revealed. Forearm and possibly brachium in males 



thickened and relatively larger in this male. Probably a general rule. 

 (p) One 30 mm. Beautiful. Long lapette with secondary one. Top of 



head reminds me in some ways of Bufo hemiophrys. 



7. In a similar way a few notes on some females are : 



(a) 18 mm. specimen 9 ? but not a male. 



(6) 18 mm. 2 transverse ridges on lower throat. Is it a 9 ? 



(c) 21.5 mm. ripe, dark throat. 



(d) 22 mm. with dark triangle on pectoral region. 



(e) 25 mm. pectoral region with prominent black spots. 



(/) 25 mm. Very dark spotted throat and breast. (To distinguish from cf 

 must look at throat vesicle. Other female throats like rest of under 

 parts. Tympanum warty or may be free of warts. Sometimes tympanum 

 in female so covered with warts tympanum is not revealed.) 9 ripe. 

 Surely a warty beast. 



(g) 25.5 mm. spent, 13 mm. wide. 



(h) 25.5 mm. ripe. Stripe more prominent in preserved 9 s, probably 

 because they are lighter, 



(i) 26 mm. Dusky throat and breast. 



(j) 26.5 mm. Throat slightly spotted with darker. 



(k) 26.5 dark, ripe. Width 19 mm. Triangle on pectoral region.
