The specimens figured by Schloenbach of this species are internal 

 casts from the Tourtia of Quedlinburg, in the Harz, where it appears 

 to be very rare. 



The shells that we have obtained from Shenley probably belong 

 to this species, but they are longer in proportion to their width 

 than the Quedlinburg specimens. The shell is longer than wide, of a 

 triangular shape, being widest at the front-margin, tapering towards 

 the beak ; both valves are convex. The larger valve has three 

 elevated angular folds, the space between them being deeply 

 furrowed ; on each side of the valve are three to five smaller folds, 

 those near the lateral margin of the shell are often obscure ; all 

 these folds extend to the extremity of the beak,which is recurved and 

 truncated by a small foramen. The smaller valve has four elevated 

 angular folds ; between these the valve is deeply sulcated. On 

 each side of the shell are three or more smaller folds ; the folds 

 on both valves extend to the front-margin, and are covered by con- 

 centric imbrications. This character was observed by Schloenbach, 

 who was doubtful whether this form should be referred to the genus 

 Megerleia or to Terebratella. This species may be a connecting- 

 link between Terebratella trifida and T. oblonga. 



We have obtained very few specimens of this form.

We have not thought it necessary to give references to the various 

 authors who have figured Kingena lima from the Chalk. This 

 species has been recorded from the Upper Chalk to the Upper Neo- 

 comian, but it can be divided into several subspecies when adult 

 specimens are examined.
