//Astron. Astrophys.// **606**, Art. No. L5 (2017).\\
8 sets of methyl silane, CH<sub>3</sub>SiH<sub>3</sub> transitions with //J'// between 4 and 16 (between 87 and 351 GHz) were detected with the IRAM 30 m telescope in emission toward the late-type C-rich star CW Leonis. The //K// levels are blended at low //J//, but partly resolved //K// level structure is seen at higher //J//. Some sets of transitions are slightly or strongly blended with emission lines of other molecules, but in all instances there are features not entirely blended.
