Abstract
On the basis of IUE data, the specific absorption features in the spectra of Ap-Si Stars are displayed in the 1250-1850 Å range and identified when possible. The contribution of the Si II multiplets is calculated in LTE for a typical overabundance x 102 of silicon. It accounts for only a small part of the observed absorption. Common unidentified structures, smaller than the 1400 Å depression are pointed out.
