The new genus Apocoleps is characterized by having 8 （vs. 6 in most other related genera） armour tiers, spines at both ends of the cell, 3 adoral organelles and plates with 4 reniform uni-windows. Apo- coleps magnus spec. nov. is defined by the following features： body elongated and slightly curved, about 100-120p.mx 3545 lam in vivo; anterior tertiary tier plate with four uni-windows, most secondary and main tier plates with four uni-windows, posterior tertiary tier plate with two uni-windows; left plate margin slightly serrated; on average 23 transverse and 22 longitudinal ciliary rows; one terminal contractile vacuole; marine habitat.展开更多

In current college English teaching, it exists module, single and dogmatic and a series of disadvantage trends, taking comprehensive practice activities as the carrier to improve college English teaching efficiency, which has a multiplier effect. This paper first analyzes the importance of comprehensive practical activities in college English teaching activities, and then it proposes a set of practicable activity strategies, hoping to play a valuable role.展开更多

Apo- coleps magnus spec. nov. is defined by the following features： body elongated and slightly curved, about 100-120p.mx 3545 lam in vivo; anterior tertiary tier plate with four uni-windows, most secondary and main tier plates with four uni-windows, posterior tertiary tier plate with two uni-windows; left plate margin slightly serrated; on average 23 transverse and 22 longitudinal ciliary rows; one terminal contractile vacuole; marine habitat.
