摩睺羅伽（摩睺此云大也羅伽云𦙄腹行也此於諸畜龍類所攝舊云蟒神者相似翻名非正對之也）。

Mahoraga (摩睺羅伽: 'maho' translates here as 'great'; 'raga' means 'crawling on belly and chest'. This belongs to the animal class of serpents/nāgas. The older translation as 'python spirit' [蟒神] is a translation by approximation and not an exact equivalent).
