Less widely distributed than M. contorta, but often very abundant and presenting a 

 considerable range of external form. Karrer's figures are somewhat confusing, for, 

 whereas the side view shows a test with angular edges, the end view portrays a round- 

 edged shell. It would therefore appear that Karrer did not attribute any special 

 importance to the sectional outline of the chambers in his species, and this would 

 appear to be a sound diagnosis, for, wherever the species occurs in any abundance, both 

 round and angular specimens are to be found. Such is the case at Kerimba, where 

 M. sclerotica is a fairly common species. At some Stns. the angular and round forms 

 occur in company, but the angular form is the more abundant and occurs alone at 

 Stns. 1 and 4. At Stn. ] B only the round form is found ; at Stn. 12 the specimens 

 are exceptionally large. A very noticeable feature at Kerimba is the nature of the 

 test. The specimens found may be separated into two groups according to the coarse- 

 ness of the arenaceous investment. At most of the Stns. the tests are very coarsely 

 arenaceous, but at Stns. 2 and 10 a very finely agglutinate test occurs in company with 

 the coarsely arenaceous individuals. 



One abnormal specimen occurred at Stn. 1 in which the last chamber became trifid 

 in mid-growth, and separated into three divisions which continued to grow and 

 terminated in three separate apertures.

Very scantily represented, but large and typical specimens were found at Stns. 5 

 and 9. At Stn. 12 a specimen with reticulate markings between the ridges occurred.

The "Planche inedite " of d'Orbigny representing specimens found in the Ped Sea 

 appears to afford the best, if not the only, illustration of a small quinquelocnline
