There are 8,400,000 forms. So "another form" means any one of them. There is no guarantee.

Lecture on SB 7.6.3 -- Vrndavana, December 4, 1975:

Now Prahlāda Mahārāja in the previous verses explained that durlabhaṁ manuṣaṁ janma: "This human form of life is durlabham, very rarely gotten." It is not so easy. There are many rascals, they say that once you come to the human form of life there is no more degradation. That is rascaldom. When Kṛṣṇa says that dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarā tathā dehāntaram-prāptir (BG 2.13), He says that "As you have changed bodies, similarly, at the end also you'll have to change the body." He never says that "You'll get again human body." Never says. Tathā dehāntara-prāptir: "Another form of life." That another form may be... There are 8,400,000 forms. So "another form" means any one of them. There is no guarantee. You cannot say that "Now I have got human form of... Again, in the next life, I also get human..." No. You can be... The evidence is Bhārata Mahārāja. He was king, emperor, very exalted position in the human form of life, but next life he got the life of a deer. This is the evidence. So how you can say that next life will be human life? No. That's not possible. According to your karma, karmaṇā daiva-netreṇa (SB 3.31.1), if you are acting like human being, then there is chance of getting human life. And if you are acting like a dog, then you must get the body of a dog. Karmaṇā daiva-netreṇa. It depends on your karma. If you simply dress like a human being and act like a dog, then you'll get a dog's body. Kṛṣṇa will give you the facility. Māyayā, (sic) yantrā-rūḍhena māyayā. Māyā.
