 prominent, obscurely tricuspid ; the two outer pairs small, narrow and sharply 

 pointed. Margin between median and inner lateral lobes rather deeply and broadly 

 excised and thickened. There is a similar but narrower excision immediately behind 

 each outer lateral lobe. Squames long and deeply fimbriate, the series extending 

 beyond the outer lobes. Circumgenital glands in four or five groups, the median — • 

 when present — contains from 1 to 3 pores only ; upper laterals 10 to 14 ; lower
