REFLEXED (reflexus, reclinatus), when the margin of a part rises 

 upwards ; DEFLEXED (deflexus), when it bends downwards. 



REVOLVED (revolutus), and INVOLVED (involutes), are also thus

COMPLICATED (complicates), is a part laid longitudinally in folds ; 

 REPLICATE (replicates), when the apex bends round, and the part is 

 thereby refolded. 



A part prolonged or distended most considerably from front to back,

 at right angles with the length of the body, it is called TRANSVERSE 

 (transversus). 



Note. Many of the general terms of other writers, of Kirby, for 

 instance, are passed over, as their signification may be found in any 

 Latin dictionary.
